In Depth | What is an Exoplanet? - Exoplanet Exploration: Planets
An exoplanet, or extrasolar planet, is a planet outside of our solar system that usually orbits another star in our galaxy. Exoplanets - planets outside our solar system - are everywhere. But why do we study them? What makes them so interesting?
Exoplanet Exploration: Planets Beyond our Solar System
Exoplanet Exploration Program NASA's science, technology and mission management office for the exploration of exoplanets. The program's primary goals, as described in the 2014 NASA Science Plan, are to discover planets around other stars, to characterize their properties and to identify planets that could harbor life.

20 Intriguing Exoplanets | NASA
Check out the astronomers' top 20 list of exoplanets below, along with artist's concepts depicting what they might look like. 1. Kepler-186f Kepler-186f was the first rocky planet to be found within the habitable zone -- the region around the host star where the temperature is right for liquid water. This planet is also very close in size to Earth
Exoplanet - Wikipedia
An exoplanet or extrasolar planet is a planet outside the Solar System. The first possible evidence of an exoplanet was noted in 1917 but was not recognized as such. [1] The first confirmation of detection occurred in 1992. A different planet, initially detected in 1988, was confirmed in 2003
What Is an Exoplanet? | NASA Space Place - NASA Science for Kids
What Is an Exoplanet? The Short Answer: All of the planets in our solar system orbit around the Sun. Planets that orbit around other stars are called exoplanets . All of the planets in our solar system orbit around the Sun. Planets that orbit around other stars are called exoplanets. Exoplanets are very hard to see directly with telescopes
Overview | Planet Types - Exoplanet Exploration: Planets Beyond our
The planets beyond our solar system are called "exoplanets," and they come in a wide variety of sizes, from gas giants larger than Jupiter to small, rocky planets about as big around as Earth or Mars. They can be hot enough to boil metal or locked in deep freeze
Lists of exoplanets - Wikipedia
As of 1 September 2022, there are 5,157 confirmed exoplanets in 3,804 planetary systems, with 833 systems having more than one planet. [1] Most of these were discovered by the Kepler space telescope
What is the Universe? | What is an Exoplanet? - Exoplanet Exploration
Earth and the Moon are part of the universe, as are the other planets and their many dozens of moons. Along with asteroids and comets, the planets orbit the Sun. The Sun is one among hundreds of billions of stars in the Milky Way galaxy, and most of those stars have their own planets, known as exoplanets
Exoplanets, worlds orbiting other stars | The Planetary Society
Exoplanets are planets that orbit other stars. Scientists think that most stars have at least one exoplanet. These worlds are a prime target for the search for life beyond Earth. You can help The Planetary Society advocate for the Roman Space Telescope, NASA's next exoplanet mission
Exoplanets | Center for Astrophysics
Exoplanets Until the 1990s, the only planets we knew existed were in orbit around the Sun. Since 1992, astronomers have discovered thousands of exoplanets: worlds in orbit around other stars. Based on the data we have, researchers think there could be hundreds of billions of planets in the Milky Way alone
What in the World is an 'Exoplanet?' - NASA
The worlds orbiting other stars are called "exoplanets," and they come in a wide variety of sizes, from gas giants larger than Jupiter to small, rocky planets about as big around as Earth or Mars. They can be hot enough to boil metal or locked in deep freeze
Exoplanets: Worlds Beyond Our Solar System | Space
Exoplanets are planets beyond our own solar system. Thousands have been discovered in the past two decades, mostly with NASA's Kepler Space Telescope. These worlds come in a huge variety of
Exoplanet Orbit Database | Exoplanet Data Explorer
The Exoplanet Data Explorer is best experienced on the latest version of Chrome or Safari. The latest version of Firefox is supported too. Due to a change in standards for the data: URL protocol, the "export" feature is now Firefox-only; Chrome and Safari will produce blank pages. Internet Explorer is not supported
Exoplanets - Understanding Evolution
Exoplanets around Sun-like stars were first detected in the 1990s, and since then, thousands are on their way to being confirmed thanks to new telescopes and instruments. In fact, the Kepler space telescope and other planet-hunting telescopes have helped astronomers
10 Things: Exoplanets 101 - NASA Solar System Exploration
In 1995, 51 Pegasi b (also called "Dimidium") was the first exoplanet discovered orbiting a star like our Sun. This find confirmed that planets like the ones in our solar system could exist elsewhere in the universe. 8—Trillions await. A recent statistical estimate places, on average, at least one planet around every star in the galaxy
EXOPLANETS -
It was the mark of sodium gas in the atmosphere of the planet. Since then, astronomers have discovered many more planets transiting their stars, and have used Hubble to investigate some of those planets' atmospheres. In the atmosphere exoplanet HD 189733 b, located 63 light-years away, Hubble detected methane
Exoplanets - National Geographic - Science
For centuries, planets beyond our solar system—called exoplanets —existed only in theory and science fiction. It seemed nearly impossible to detect planets light-years away, since the
EarthSky | What are exoplanets?
Exoplanets are planets that orbit a star other than our sun. The prefix exo comes from the Greek and means outside; these worlds are far, far outside our own solar system. Astronomers have
