Other Planets?

Question

Its been said that on the other side of our sun that there is a line of planets just like ours but we cant get to it due to the sun and we cant get there cause it would take to long. How true is this information and is there any current informationt that you could tell me.

Answer 1

This is a science fiction notion that you have picked up. It revolves around the idea of a counter-Earth hiding 180 degrees away from us behind the Sun, keeping out of sight. Your source has added the complexity of a counter-Mars 180 degrees away from Mars and a counter-Jupiter 180 degrees deom its counterpart etc.

Please read about Lagrangisn points L1 to L6 at the link below and note the following paragraphs:

"L3
The L3 point lies on the line defined by the two large masses, beyond the larger of the two.

Example: L3 in the Sun–Earth system exists on the opposite side of the Sun, a little outside the Earth's orbit but slightly closer to the Sun than the Earth is. Here, the combined pull of the Earth and Sun again causes the object to orbit with the same period as the Earth.

The Sun–Earth L3 point was a popular place to put a "Counter-Earth" in pulp science fiction and comic books - though of course, once space based observation was possible via satellites and probes, it was shown to hold no such object.

In actual fact, Sun–Earth L3 is highly unstable, because the gravitational forces of the other planets outweigh that of the Earth (Venus, for example, comes within 0.3 AU of L3 every 20 months)."

The point that rockets and probes can act like a periscope and look round corners and behind the Sun for us seems to have eluded some posters, No chance of hypothetical planets playing Hide-and-Seek with us when we have eyes (cameras) everywhere!

Answer 2

That wouldn't make any sense, because our eight planets make a complete revolution around the sun. And because our planet is one of the inner planets, one revolution takes a considerable less time than our former planet Pluto. Thus we would be able to see what is behind the sun before these supposed planets could hide from us again. Even if it were an extremely close orbit to the sun, that would make it revolve around the sun faster than ours making it appear one time or another.

However, astronomers make the suggestions that a planet exists by its gravitational influence on neighboring objects such as the sun, stars or other planetary objects. Because the scientific community has not come forth with such claims, though not impossible it's doubtful.

Answer 3

That is not true. The orbits of such planets would inevitably bring them out from behind the Sun and in view of Earth. Even a planet in exactly the same orbit as Earth but 180 degrees around on the other side of the Sun would not stay there. On long time scales orbital mechanics tells us that such an arrangement is unstable and the hypothetical other planet would slowly, over many centuries, drift along its orbit to move out from behind the Sun.

Answer 4

This makes no sense. The planets aren't lined up in a line on one side of the sun (like you sometimes might see in pictures). They all go around the sun at different speeds

Answer 5

That is a load of crap, we would know for sure if there were other planets in our solar system.

Answer 6

not true, those planets that you may be saying may be in fact from other solar systems..

Answer 7

Uh. Not that I'm aware of.

Answer 8

not in our solar system.

Answer 9

this is total bull.

Answer 10

no!!!
this is not true at all !!!!
