The nearest-known exoplanet is a small, probably rocky planet orbiting Proxima Centauri – the next star over from Earth. A little more than four light-years away, or 24 trillion miles.
How many light-years away is the nearest exoplanet?
The closest exoplanet found is Proxima Centauri b, which was confirmed in 2016 to orbit Proxima Centauri, the closest star to the Solar System (4.25 ly).
How long would it take to get to the closest exoplanet?
So 1,400 light-years equals about 8.2 quadrillion miles. If we took one of our fastest probes to the planet, New Horizons, which is currently traveling about 36,000 miles per hour (50,000 km/h), it would take well over 26 million years to reach our destination.
How far away is the nearest habitable exoplanet?
4.2 light-years Possible Third Planet Spotted around Proxima Centauri, Our Sun's Nearest Neighbor Star. The sun's nearest neighbor may actually host three planets, a new study reports. Astronomers have found evidence of a third planet circling Proxima Centauri, a red dwarf star that lies a mere 4.2 light-years from our solar system.
What’s the closest exoplanet?
Proxima Centauri b Proxima Centauri b is located just four light-years away from Earth, making it Earth's closest known exoplanet, according to NASA Exoplanet Exploration. The exoplanet, which was discovered in 2016, has a mass that is 1.27 times that of Earth's.
Is there an exoplanet in our solar system?
In 1990, we only knew of the planets in our own Solar System. Today, the exoplanet count is more than 5000.
How many stars are within 10 light-years of Earth?
As of October 2012, astronomers have been able to detect planets in the Solar System and around Alpha Centauri B and Lalande 21185 among the nearest 12 stars….Stars within 10 light-years.

How long would it take to go 4.2 light years?
about 6,300 years Proxima Centauri is 4.2 light-years from Earth, a distance that would take about 6,300 years to travel using current technology. Such a trip would take many generations.
How many light years away is Kepler-452b?
1,402 light yearsKepler-452b / Distance to Earth Kepler-452 is about 1,800 light years away, which means it currently would take a spacecraft about 30m years to travel there. At least one planet is orbiting the star: it's called Kepler-452b, and astronomers have wondered whether it could be home to alien life.
How far away is exoplanet Kepler 452b?
1,402 light yearsKepler-452b / Distance to Earth The planet is about 1,800 light-years (550 pc) away from the Solar System. At the speed of the New Horizons spacecraft, at about 59,000 km/h (16,000 m/s; 37,000 mph), it would take approximately 30 million years to get there.
