What are the most Earth-like worlds we''ve found?

Other galaxies could be full of sibling Earths: In fact, evidence suggests there may be as many as one Earth-like planet for every five Sun-like stars in the Milky Way alone. Earth is our home, which makes it special in its own right. But there could be countless more like it waiting to be found or even born. The ongoing hunt for Earth-like

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 []

Cosmic Milestone: NASA Confirms 5,000 Exoplanets

The 5,000-plus planets found so far include small, rocky worlds like Earth, gas giants many times larger than Jupiter, and "hot Jupiters" in scorchingly close orbits around their stars. There are "super-Earths," which are possible rocky worlds bigger than our own, and "mini-Neptunes," smaller versions of our system''s Neptune.

Planetary system

Example of a system ()Planetary systems, usually simply referred to as ''systems'', are gravitationally bound collections of orbitally organized planets, planetoids and asteroids around a governing star or group of stars.The gravitational stress of the central objects allows the formation of Jump Points between systems, which allow near-instantaneous interstellar travel.

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. Well, there is only one Solar System in our galaxy, as only ours is officially called so. But astronomers have found more than 3,200 other stars with planets orbiting them in the Milky Way.

Exoplanets

Overview Most of the exoplanets discovered so far are in a relatively small region of our galaxy, the Milky Way. ("Small" meaning within thousands of light-years of our solar system; one light-year equals 5.88 trillion miles, or 9.46 trillion kilometers.) Even the closest known exoplanet to Earth, Proxima Centauri b, is still about 4 light-years []

Are We Alone?

The search for life beyond Earth is really just getting started, but science has an encouraging early answer: there are plenty of planets in the galaxy, many with similarities to our own. But what we don''t know fills volumes. Observations from the ground and from space have confirmed thousands of planets beyond our solar system. []

Exoplanets

Our understanding of planets beyond our own solar system is still in its infancy. Because planets in other solar systems are extraordinarily difficult to see directly, astronomers have had to come up with innovative ways to hunt for them. Only recently have our technology and techniques been up to the task of finding exoplanets.

Planets Around Other Stars

Throughout recorded history and perhaps before, we have wondered about the possible existence of other worlds, like or unlike our own. The earliest understanding of the solar system showed us that there were indeed other worlds in orbit about our Sun, and steadily growing understanding of their natures shows that all are dramatically different from Earth, and
