Exoplanets are planets beyond our own solar system. Thousands have been discovered in the past two decades, mostly with NASA's Kepler Space Telescope. These worlds come in a huge variety of sizes and orbits.Mar 29, 2018

What is the next solar system after ours?
Now we know of two planets around Proxima Centauri. Since 2016, astronomers have known that the solar system next door to ours—a triple-sun system—has one planet, Proxima b, located in the so-called habitable zone.
What is beyond our galaxy?
Beyond our galaxy itself, which holds our solar system and everything beyond it, are other galaxies. The nearest galaxy is Andromeda, which will collide with the Milky Way galaxy in about 4 billion years. The Milky Way is part of the Local Group, which consists of 30 galaxies.
Is there anything beyond our solar system?
In a milestone for astronomy – and possibly the search for extraterrestrial life – NASA's Jet Propulsion Laboratory confirmed there are now 5,000 known planets beyond our solar system. These so-called exoplanets include rocky worlds roughly the size of Earth, gas giants larger than Jupiter and "mini-Neptunes."
What is over the solar system?
Beyond our own solar system, there are more planets than stars in the night sky. So far, we have discovered thousands of planetary systems orbiting other stars in the Milky Way, with more planets being found.
How long would it take to go 4 light-years?
Last year, astronomers raised the possibility that our nearest neighbor, Proxima Centauri, has several potentially habitable exoplanets that could fit the bill. Proxima Centauri is 4.2 light-years from Earth, a distance that would take about 6,300 years to travel using current technology.
What is the new planet discovered in 2020?

Will humans ever leave the Milky Way?
So, to leave our Galaxy, we would have to travel about 500 light-years vertically, or about 25,000 light-years away from the galactic centre. We'd need to go much further to escape the 'halo' of diffuse gas, old stars and globular clusters that surrounds the Milky Way's stellar disk.
Will humanity ever leave the solar system?
Humans will never migrate to a planet outside of Earth's solar system because it would take far too long to get there, Swiss Nobel laureate Michel Mayor said Wednesday.
What planets are in Andromeda?
Does the Andromeda Galaxy have planets? There is currently only one very strong candidate planet in the Andromeda Galaxy, temporarily named PA-99-N2. It was detected because of a microlensing event in 1999.
