[music]

00:00:04

what we can observe is a

00:00:07

scorched or icy desert, the fact that

00:00:10

life originated on our earth, has survived and

00:00:13

continues to develop for

00:00:15

billions of years,

00:00:16

it happened thanks to a number of

00:00:17

circumstances, among them, how

00:00:21

our solar system works and our

00:00:23

location in the galaxy, our system

00:00:26

is located in the Orion Arm in a relatively

00:00:29

quiet region we are not inside a globular

00:00:31

cluster

00:00:32

to the nearest star a little more than 4

00:00:35

light years we are far twenty-five

00:00:37

thousand light years from the center of

00:00:40

the galaxy which is a much more

00:00:42

star-populated region if

00:00:45

we do not meet a single star on the way to Proxima Centauri

00:00:49

then there at the same distance, well, you

00:00:51

met hundreds and even thousands of stars,

00:00:54

we have only one star, the sun, in fact,

00:00:58

approximately 99.9 percent of the mass of the entire

00:01:02

solar system is the

00:01:03

sun, the remaining fraction of a

00:01:05

percent is all the planets and satellites,

00:01:08

asteroids and comets,

00:01:09

with such a dominant mass, the sun It is

00:01:11

quite clear how the movement of a

00:01:14

body in a system is organized and how planets

00:01:16

exist quite stably in their orbits

00:01:19

for

00:01:20

ards of years, and if there is not one star like our

00:01:23

sun, but there are 2 or more of them, can a

00:01:27

planet form in such a system

00:01:29

and even exist stably, what

00:01:31

will its orbit be?

00:01:33

after the first two videos about double and

00:01:35

multiple stars, the question about the presence of planets in

00:01:37

such systems was raised quite often;

00:01:40

some generally doubted that planets

00:01:42

in such systems were possible in principle, and

00:01:43

this is a fairly fair question, because

00:01:46

quite recently scientists and we ourselves

00:01:48

knew whether this is what we are talking about

00:01:51

finally, let's talk in this video if, according to

00:01:57

modern estimates, the number of planets in

00:01:59

our galaxy can reach a

00:02:01

trillion, and at the same time, perhaps

00:02:03

most stars are in double and

00:02:05

multiple systems, is this entire

00:02:07

trillion planets located only in

00:02:09

single stars, now we already know that

00:02:12

this is not so and planets in multiple systems

00:02:14

have been discovered, although so far not very many

00:02:17

of the almost 4000 confirmed exoplanets

00:02:21

and another four and a half thousand

00:02:22

candidates, today

00:02:24

there are about 130 planets in binary

00:02:27

systems and about 30 systems with more

00:02:30

multiples,

00:02:31

but if there are two stars in the system, then

00:02:34

what will there be around rotating planet,

00:02:36

here two types of systems are distinguished according to their

00:02:38

orbits of planets, and

00:02:40

from the type such planets revolve around

00:02:43

one of the components in a binary system,

00:02:45

in theory, both components can have their own

00:02:48

planets and Petipa planets,

00:02:50

they are also called planets with multiple

00:02:52

orbits, they already rotate in a

00:02:55

wider orbit around two stars

00:02:58

around a single object, of course,

00:03:00

there are restrictions and certain

00:03:03

conditions under which such planets can

00:03:05

have orbital lines, but what about

00:03:08

the formation of such planets, because usually

00:03:10

models of the formation of planets esprado

00:03:12

planetary disk by accretion

00:03:14

are considered in the context of a single star;

00:03:17

in general, this issue is not simple and

00:03:19

deserves a separate discussion I will just

00:03:21

briefly mention a couple of options; of course, the

00:03:24

presence of 2 stars complicates the task and

00:03:27

introduces disturbance in the formation of planets;

00:03:29

however, simply planetary disks in such

00:03:31

systems have

00:03:32

already been discovered; secondly, planets

00:03:34

can initially form into a

00:03:36

single star and subsequently be

00:03:38

captured by a double system, and such

00:03:41

examples have already been discovered and now

00:03:43

Let's finally look at a few

00:03:45

examples of such planets with their interesting

00:03:47

features.

00:03:49

In the first video on this topic, I remembered

00:03:52

Tatooine from Star Wars

00:03:53

and we also did our own demonstration of

00:03:56

how someone could

00:03:57

see the sky in a system with several

00:03:59

stars. It even seemed to someone that

00:04:01

such a planet was destiny fiction,

00:04:03

however, a similar object has already been discovered;

00:04:06

this kepler-16b is

00:04:08

one of the few confirmed planets with a

00:04:11

multiple orbit,

00:04:12

that is, a planet that revolves

00:04:14

around two stars of an orange and a red

00:04:17

dwarf,

00:04:18

however, unlike the year and which would be

00:04:20

completely habitable kpler-16b

00:04:23

is a cold gas giant the size of

00:04:25

Saturn,

00:04:26

but it would not have been possible to stand on a solid surface

00:04:27

there; the

00:04:29

race created such a simulation of the type

00:04:32

that could be on the hypothetical

00:04:34

satellites of such a planet;

00:04:36

here is the planet itself and its parent

00:04:38

stars; planet ps or by 1620 26 b,

00:04:44

which is also unofficially called

00:04:46

Methuselah, one of the oldest known

00:04:48

exoplanets,

00:04:50

its age is about 12.7 billion years, which is

00:04:54

only a billion years younger than the

00:04:56

universe itself and almost 3 times older than the earth,

00:04:59

the planet rotates in a binary system, it is

00:05:02

also a Petipa planet with a multiple orbit and

00:05:05

like Kepler 16,

00:05:06

but it rotates around completely

00:05:08

different stars,

00:05:09

namely a white dwarf and a pulsar, and the entire

00:05:13

system is also located inside the

00:05:15

globular cluster M4 close to its

00:05:18

center for a long time, scientists generally

00:05:20

questioned the very possibility of the existence of

00:05:23

planets in globular clusters due to the fact that

00:05:25

globular clusters are so ancient and there are

00:05:27

very few heavier elements for

00:05:30

formations of planets on planets were

00:05:32

discovered Ethan Methuselah's fate is very

00:05:35

interesting initially, it probably

00:05:37

formed from a single star

00:05:38

similar to our sun and then

00:05:40

migrated closer to the center of the M4 cluster and

00:05:43

was captured by a double star

00:05:45

Methuselah's parent star was

00:05:47

thrown out of the system and in the process of

00:05:49

evolution the two stars turned white dwarf

00:05:52

and pulsar and what about triple systems

00:05:56

and are there any planets in

00:05:59

multiple systems not far from our

00:06:01

sun, if of course you can use

00:06:03

the word close in relation to interstellar

00:06:06

distances to there is and you can say nowhere closer

00:06:10

in 2016 an exoplanet was discovered near the one

00:06:14

closest to us the stars Proxima Centauri,

00:06:16

which is supposedly part of the

00:06:19

triple system, the planet Proxima

00:06:21

Centauri by is comparable in size to the earth

00:06:23

and is even in the so-called

00:06:25

habitable zone, that is, at what

00:06:27

distance from the star at which water on the

00:06:30

surface could be in a liquid

00:06:32

state, and even though liquid water is

00:06:34

one of the key factors for the

00:06:37

existence of the life that we know

00:06:39

must be present, and others must be present,

00:06:42

in particular the atmosphere to regulate

00:06:44

the climate, maintaining the necessary

00:06:46

pressure for protection from harmful cosmic

00:06:48

radiation, and so on, and no matter how tempting it may be,

00:06:52

having discovered an earth-like planet near the

00:06:54

star closest to us, already make plans

00:06:57

about sending a generation ship there or

00:07:00

getting in touch with Proxima Centauri

00:07:03

persons, it looks like we will have to hold back the welded

00:07:07

rocket horses at the red dwarf

00:07:09

Proxima Centauri,

00:07:11

super-powerful flares have been recorded, which apparently

00:07:14

happen quite often and affect the planet with

00:07:16

the strongest radiation, evaporating the

00:07:18

potential atmosphere and actually

00:07:20

sterilizing the planet, so most likely

00:07:23

it is unsuitable for life, which I don’t know, but here is

00:07:25

an image in the

00:07:28

artist’s imagination of what

00:07:29

the surface of this planet might look like: a lifeless

00:07:32

desert and you and the stars time,

00:07:36

most exoplanets are now being

00:07:37

discovered by indirect methods, one of the

00:07:40

few exoplanets observed

00:07:42

directly, fomalhaut bit is also one

00:07:44

of the exoplanets of which already there is a

00:07:46

full name Dagon the star Fomalhaut is

00:07:50

probably part of a triple

00:07:51

star system and perhaps Dagon is not the

00:07:54

only planet this parent

00:07:56

star has, there may be two or even three

00:08:00

another triple system with the planet hd

00:08:03

1887 53

00:08:05

it consists of a star similar to our

00:08:07

sun and at a distance approximately

00:08:09

equal to the distance from our sun to

00:08:12

Saturn,

00:08:15

red and orange dwarfs that are close to each other revolve around the first star, a

00:08:17

planet that

00:08:20

belongs to the class of hot Jupiters,

00:08:22

that is, it is a gas giant located

00:08:25

very close to the star, orbits the

00:08:27

first star with a period of only three and a

00:08:30

half days if this planet has

00:08:33

a satellite, this is how the sky may look on

00:08:35

it,

00:08:37

but this is not the limit of the planets were

00:08:40

discovered and in quadruple stars, for example, the

00:08:44

30 Aries system consisting of two

00:08:46

double stars rotating around a common

00:08:49

center of mass in this system, a

00:08:51

rotating planet was discovered in one of the pairs

00:08:54

around one of the components and probably an

00:08:56

even more interesting planet

00:08:58

Page van Bee in the Kepler 64 system which,

00:09:01

unlike the first example of the type,

00:09:03

is a planet from a multiple orbit

00:09:06

or a Petipa planet, that is, also in a

00:09:08

quadruple system consisting of two pairs of

00:09:10

stars, it does not revolve around one

00:09:12

star and around the pair

00:09:14

as already mentioned without arbi 1620 for 6 b

00:09:17

or tatooine like kepler-16b

00:09:20

and this is only the beginning, until quite recently

00:09:24

it was considered unlikely that the existence of

00:09:27

planets in multiple systems, now with the

00:09:29

discovery of those objects that I

00:09:31

talked about with the development of new technologies,

00:09:33

we understand that in everything in the universe is

00:09:35

even more interesting and complex than

00:09:38

we previously thought, and scientists are also

00:09:40

trying to answer the question: can

00:09:42

such planets be suitable for life? They,

00:09:44

like you, planets of single stars

00:09:47

may have their own habitable zones; in

00:09:50

addition, studies are coming out that

00:09:52

study this question more deeply, taking into

00:09:54

account factors such as the stability of orbits

00:09:57

and many others, with

00:09:58

this video I am finishing the 3rd
