What is the darkest exoplanet?
TrES-2b is an extrasolar planet orbiting the star GSC 03549-02811 located 750 light years away from the Solar System. The planet has been identified in 2011 as the darkest known exoplanet, reflecting less than 1% of any light that hits it.
Which exoplanet is least massive?
Planet Gliese 581 e orbits its host star – located only 20.5 light-years away in the constellation Libra (“the Scales”) — in just 3.15 days. “With only 1.9 Earth-masses, it is the least massive exoplanet ever detected and is, very likely, a rocky planet”, says co-author Xavier Bonfils from Grenoble Observatory.
What is the closest exoplanet to Earth?
At only four light-years away, Proxima Centauri b is our closest known exoplanet neighbor. Proxima b is a super Earth exoplanet that orbits a M-type star. Its mass is 1.27 Earths, it takes 11.2 days to complete one orbit of its star, and is 0.0485 AU from its star. Its discovery was announced in 2016.
How many Super Earths are there?
In June 2008, European researchers announced the discovery of three super-Earths around the star HD 40307, a star that is only slightly less massive than our Sun. The planets have at least the following minimum masses: 4.2, 6.7, and 9.4 times Earth’s.
What planet rotates the fastest?
Jupiter is the fastest spinning planet in our Solar System rotating on average once in just under 10 hours. That is very fast especially considering how large Jupiter is. This means that Jupiter has the shortest days of all the planets in the Solar System.
What is the scariest planet?
Welcome to TrEs-2b, the planet of eternal night. The darkest planet ever discovered orbiting a star, this alien world is less reflective than coal with a burning atmosphere – the air is as hot as lava.
Is the diamond planet real?
In October 2012, it was announced that 55 Cancri e showed evidence for being a carbon planet. It has eight times the mass of Earth, and twice the radius. Research indicates that the 2,150 °C (3,900 °F) planet is “covered in graphite and diamond rather than water and granite”.
What is the most dangerous planet?
0.015% 0.007% 3.5% 64% Page 2 Venus is the most dangerous planet in the solar system: its surface is at 393°C, hot enough to melt lead. It’s even hotter than the planet Mercury, which is closest to the Sun. Venus’ atmosphere is acidic and thick.
What is the longest planet name?
Jupiter: Our Solar System’s Largest Planet
- Jupiter is the largest planet in the solar system. …
- Jupiter helped revolutionize the way we saw the universe and ourselves in 1610, when Galileo discovered Jupiter’s four large moons — Io, Europa, Ganymede and Callisto, now known as the Galilean moons.

How far away is the closest habitable planet?
The closest alien planet to our solar system is even more Earth-like than scientists had thought, new observations suggest. In a new study, an international team of researchers found that the minimum possible mass for Proxima b, which lies just 4.2 light-years from Earth, is just 17% more massive than our planet.
What planets can sustain life?
A 2015 review concluded that the exoplanets Kepler-62f, Kepler-186f and Kepler-442b were likely the best candidates for being potentially habitable. These are at a distance of 1,200, 490 and 1,120 light-years away, respectively.
What planet is most like Earth?
Kepler-452b (a planet sometimes quoted to be an Earth 2.0 or Earth’s Cousin based on its characteristics; also known by its Kepler Object of Interest designation KOI-7016.01) is an exoplanet orbiting the Sun-like star Kepler-452 about 1,402 light-years (430 pc) from Earth in the constellation Cygnus.
Which planet can we live on?
After the Earth, Mars is the most habitable planet in our solar system due to several reasons: Its soil contains water to extract. It isn’t too cold or too hot. There is enough sunlight to use solar panels.
