Aug 24, 2016 · (CNN)In a discovery that has been years in the making, researchers have confirmed the existence of a rocky planet named Proxima b orbiting Proxima Centauri, the closest star to our sun, according to a new study.
At 4.2 light years away Proxima Centauri is the nearest star to the sun, but as it is so small and dim it cannot be viewed with the naked eye.
The stability of the Solar System is a subject of much inquiry in astronomy.Though the planets have been stable when historically observed, and will be in the short term, their weak gravitational effects on one another can add up in unpredictable ways.
We’ve just passed a series of 3 full supermoons. The next supermoons of 2018 will be the new moons of June, July and August. A supermoon is a new or full moon closely coinciding with perigee, the moon’s closest point to Earth in its monthly orbit. According to the original definition of

Closest Star. You might have heard that it’s Alpha Centauri, the third brightest star in the sky, just 4.37 light-years from Earth. But Alpha Centauri isn’t one star, it’s a system of three stars. First, there’s a binary pair, orbiting a …
Proxima Centauri, a red dwarf outlier in the Alpha Centauri system, is the nearest star other than the sun. It is 4.22 light-years from Earth.
You can see thousands of stars when you look up at night. Here are the top 10 closest stars to our Sun. The closest one is 4.2 light-years away from us.

Discovery: Prior to its discovery, astronomers believed that the Sagittarius Dwarf Galaxy was the closest galactic formation to our own. At 70,000 light years from Earth, this galaxy was determined in 1994 to be closer to us than the Large Magellanic Cloud (LMC), the irregular dwarf galaxy that is located 180,000 light years from Earth, and
