Proxima Centauri b | Proxima Centauri | 11.186 |

What is the closest exoplanet?
COCONUTS-2b
Not only is COCONUTS-2b (named for the COol Companions ON Ultrawide orbiTS survey) the closest directly imaged exoplanet to Earth to date – at a distance of just 35 light-years – it’s a rarity among exoplanet discoveries: a relatively cool, massive gas giant, orbiting its star at a great distance.
What stars have exoplanets?
The stars with the most confirmed planets are Sol (the Solar System’s star, also referred to as the Sun) and Kepler-90 with 8 confirmed planets each, followed by TRAPPIST-1 with 7 planets….Multiplanetary systems.

How long would it take to get to Kepler 20b?
This week astronomers announced planet Kepler 22-b lying 600 light years or 3,527,175,223,910,165 or three and a half quadrillion miles away and 2.4 times the size of the earth. Using a space shuttle, it would take 23.4 million years to reach it.
How long would it take a radio message to get from Earth to a planet in the Kepler 62 system?
12 years
The messages will be transmitted to two stars, named Tau Ceti and Kepler 62. Because Tau Ceti is only 12 light-years from Earth, the radio signals will reach that system in 12 years.
Could there be more habitable exoplanets than Earth?
A team of scientists led by Washington State University (WSU) geobiologist Dirk Schulze-Makuch has identified two dozen exoplanets that could be more favorable to life than the Earth. Based on data from the Kepler mission, these super-habitable worlds may have conditions more suitable for sustaining life for a longer period of time than our planet.
How many exoplanets do stars have?
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 WFIRST, NASA’s next exoplanet mission. You can also support our efforts to help scientists find 100 Earth-sized exoplanets around nearby stars. Why study exoplanets?
What has the Planetary Society done to help us find exoplanets?
Since 2009, Planetary Society members have supported work by Debra Fischer, one of the world’s top exoplanet researchers. These projects have greatly improved our ability to search for Earth-like exoplanets. We’ve been working with Fischer on exoplanet projects since 2009.
Is there life on other planets?
While no direct evidence of such life has been discovered, exoplanet-hunting missions like Kepler have changed many of our ideas about how planetary systems are formed and have provided scientists with the means to think about life beyond our solar system without leaning so heavily on conjecture and speculation.
