Frequently Asked Questions

What is the nearest exoplanet?

Closest exoplanet to the Solar system is Proxima Centauri b, located approximately 4.24 light-years (1.30 parsecs) from the Sun. Several exoplanets have been discovered orbiting Barnard's Star, which is the second closest star system to the Sun, at a distance of about 5.96 light-years (1.83 parsecs).

What methods are used to discover exoplanets?

Exoplanets are discovered mainly using the transit method, radial velocity method, direct imaging, and gravitational microlensing. These techniques allow astronomers to detect planets orbiting stars outside our solar system.

How many exoplanets have been discovered?

As of now, more than five thousand exoplanets have been discovered orbiting stars outside our solar system. The exact number continues to grow as new discoveries are made using various detection methods.

What is the closest habitable planet?

The nearest potentially habitable exoplanet is Proxima Centauri b, located approximately 4.24 light-years (1.30 parsecs) from the Sun. It orbits within the habitable zone of its star, where conditions might be suitable for liquid water to exist.

Exoplanètes

Les exoplanètes sont des planètes qui orbitent autour d’étoiles situées en dehors de notre système solaire. Depuis la première découverte confirmée en 1992, les astronomes ont identifié près de 6 000 exoplanètes, et beaucoup d'autres attendent d'être confirmées. Ces planètes présentent une grande variété de tailles et de types, allant des géantes gazeuses plus grandes que Jupiter aux planètes rocheuses semblables à la Terre, en passant par des planètes errantes qui ne tournent autour d’aucune étoile.
