Learn how astronomers have found more than 3,200 planets orbiting other stars in our galaxy, and what they are like. See illustrations and videos of diverse and fascinating exoplanets, and how NASA missions.
Even our closest neighboring stars are trillions of miles away. And all stars are.
So far, the planets outside our solar system have proven to be fascinating and diverse. One planet, known as HD 40307g, is a “super Earth,” with a mass about eight times that o.

Since operations began on Oct. 1, 1958, NASA has been exploring our solar system and the stars beyond. The sun is just one out of more than 100 billion stars in our Milky Way galaxy—and these far-flung stellar bodies offer scientists some of the best clues to finding new planets.. Astronomers use geometry to determine the distance of stars from Earth.

Only 15% of stars in the galaxy host planetary systems, and one of those stars is our own sun. Revolving around the sun are eight planets. The planets are divided into two categories based on their composition, terrestrial and Jovian. Terrestrial planets, including Mercury, Venus, Earth, and Mars are primarily made of rocky material.
Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids. Beyond our own solar system, there are more planets than stars in the night sky.
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 []

By studying different solar systems, scientists can learn more about how planets form and evolve. This knowledge helps us understand our own Solar System''s history and development. Potential for Life: Discovering solar systems with planets in habitable zones increases the chances of finding extraterrestrial life.
Our solar system is just one specific planetary system—a star with planets orbiting around it. Our planetary system is the only one officially called "solar system," but astronomers have discovered more than 3,200 other stars with planets orbiting them in our galaxy. That''s just how many we''ve found so far.
