(Reuters) 鈥 European astronomers have found 32 new planets outside our solar system, adding evidence to the theory that the universe has many places where life could develop.Scientists using the European Southern Observatory telescope didn't find any planets quite the size of Earth or any ...

The discovery of more objects larger than asteroids but smaller than planets around the same time led astronomers to conclude that there must be hundreds of these Pluto-sized objects in the far reaches of the solar system. Now we have found another one, currently designated 2015 RR245. Another...
Most planets outside our solar system have been found using the radial velocity method, which measures the gravitational wobble in the star induced by the orbiting planet. The transit method would seem at first to be impractical because it requires a lucky break: The orbital plane of the planet...

Compared with it, our solar systemseems almost tiny. The distance between Pluto and the sun is “just" 5.9 billion kilometers! Pluto was onceconsidered the farthest planet in our solar system, but actually it is a dwarf planet.Besides these two planets,there are two others, which are as ...
The object was discovered as part of the team's ongoing hunt for unknown dwarf planets and Planet X. The computer simulations showed that not only was 2015 TG387's orbit stable for the age of the Solar System, but it was actually shepherded by Planet X's gravity, which keeps the smalle...

NASA researchers on Tuesday confirmed the discovery of 1,284 new planets, including nine that could support life, nearly doubling the number of confirmed planets. Ellen Stofan, chief scientist at NASA, said in a press release that the research on planets orbiting stars outside our solar system,...
