In the last years , we have discovered many planets outside our solar system.The grater part is giant gaseous.It is currently sometimes impossible to detect EartLike plantes around other stars.There are a lot of difficulty.What do you know about this?

Planets like earth are really hard to find. But I just heard in the news last month that the NASA found a planet that looks like Earth some distant away in our solar system. The planet really looks like the Earth. It's temperature and humidity are just like Earth. It is to believed that the planet also has water in it. Hopefully the planet can be lived by humans.

The Earth-like planet they discovered isn't in our Solar System, it is 20 light years away.

Yah! That's what I said. Some distant away from our solar system. I mean it is outside the solar system.

Planets of any size are very difficult to see around distant stars. Currently, detecting the "wobble" of a star due to the gravitational interactions between the star and orbiting planet has helped us discover planets usually much larger than Jupiter.
They did just discover an Earth-like planet around a star that is relatively close (just over 20 light years away), it is around a fairly small star but orbits very close so will have similar temps to that of Earth which has led astronomers to believe that there is a decent possibility for there being water. The planet is larger and more massive so will have a stronger gravity that we are used to here.
Hopefully they will continue to refine the techniques and technologies used to find planets. It will be very interesting to find out more about the planet that is somewhat similar to Earth.
