List of potentially habitable exoplanets

This is a list of exoplanets within the circumstellar habitable zone that are either under 10 Earth masses or smaller than 2.5 Earth radii, and thus have a chance of being rocky. [3] [1] Note that inclusion on this list does not guarantee habitability, and in particular the larger planets are more unlikely to have a rocky composition. [4]Earth is included for both comparison and reference

How Many Planets are in the Milky Way?

How Many Solar Systems are in the Milky Way? You might think our Solar System is unique, but there are over 5,000 solar systems that have been discovered already and are closely analyzed. Every year, scientists learn more and more solar systems, which are either different, similar, or unlike ours. They also discover new solar systems every year.

Moons of Our Solar System

How Many Moons Are in Our Solar System? Naturally-formed bodies that orbit planets are called moons, or planetary satellites. The best-known planetary satellite is, of course, Earth''s Moon. Since it was named before we learned about other planetary satellites, it is called simply "Moon." According to the NASA/JPL Solar System Dynamics team, the current tally []

Galaxies

The Sun will likely be flung into a new region of our galaxy, but our Earth and solar system are in no danger of being destroyed. Andromeda, also known as M31, is now 2.5 million light-years away, but it is inexorably falling toward the Milky Way under the mutual pull of gravity between the two galaxies and the invisible dark matter that

Our Sun: Facts

The Sun has been called by many names. The Latin word for Sun is "sol," which is the main adjective for all things Sun-related: solar. This illustration shows the spiral arms of our Milky Way galaxy. Our Sun is in the Orion Spur. The Sun orbits the center of the Milky Way, bringing with it the planets, asteroids, comets, and other

List of nearest exoplanets

The closest exoplanets are those found orbiting the star closest to the Solar System, which is Proxima Centauri 4.25 light-years away. The first confirmed exoplanet discovered in the Proxima Centauri system was Proxima Centauri b, in 2016. HD 219134 (21.6 ly) has six exoplanets, the highest number discovered for any star within this range.

Where Are We In The Milky Way | Milky Way Facts

The name of our home galaxy, like the names of many other astronomy objects, came from the ancient Greek and Roman cultures. Both the Greeks and Romans saw the starry band as the river of milk. Our Solar System is placed between two main arms — Scutum-Centaurus and Perseus, within the small partial arm named the Orion Arm or Orion Spur.

Exoplanets, worlds beyond the Solar System
