What is in the center of Milky Way?
The Galactic Center (or Galactic Centre) is the rotational center, the barycenter, of the Milky Way galaxy. Its central massive object is a supermassive black hole of about 4 million solar masses, which powers the compact radio source Sagittarius A*, which is almost exactly at the galactic rotational center.
Are there seven planets?
While all 7 planets are considered to be roughly Earth-sized, they are each about 8% less dense than our home planet, meaning their makeup, while potentially similar to Earth, in terms of elements like iron, is significantly different in percentages.

Are there any exoplanets that look like Earth?
Now researchers think they’ve found a fourth. Planet KOI-456.04, as it’s called, appears similar to Earth in size and orbit, raising new hopes we’ve found perhaps the best candidate yet for a habitable exoplanet that resembles our home world.
Which is the closest star to the Earth?
The newly discovered exoplanet AU Mic b is about the size of Neptune. This artist’s impression shows a view of the surface of the planet Proxima b orbiting the red dwarf star Proxima Centauri, the closest star to the Solar System. Proxima b is a little more massive than the Earth.
Are there any planets similar to Earth in space?
Out of a new discovery of 104 exoplanets, astronomers found four similar in size to Earth that are orbiting a dwarf star. Two of them have the potential to support life. The craft depicted in this illustration is the NASA Kepler Space Telescope, which has helped confirm the existence of thousands of exoplanets.
Are there any planets around a single star?
View this and many more images, as well as several videos, in an extensive multimedia gallery highlighting this discovery. NASA’s Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star.
