What are the 2 exoplanets?

An international team of astronomers reports the detection of two new exoplanets orbiting an evolved sun-like star known as HD 137496. The newly found extrasolar worlds, identified using NASA’s Kepler spacecraft, were classified as hot super-Mercury and cold Jupiter.

What is the nearest exo planet?

Proxima Centauri b
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). HD 219134 (21.6 ly) has six exoplanets, the highest number discovered for any star within this range. Most known nearby exoplanets orbit close to their stars.

Are there any exoplanets like Earth?

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 Pluto an exoplanet?

Is Pluto an Exoplanet? Pluto isn’t an exoplanet; it is a dwarf planet. It can’t be considered an exoplanet since it orbits our Sun and not some other star. For a long time, Pluto was considered a planet, just like Earth; however, scientists revised the definition of a planet.

Can we live in Proxima b?

Scientists think that there could possibly be life at Alpha Centauri, and Proxima b is currently thought to be the most likely habitable world in the system, with its Earth-like size and distance from its star.

Do dwarf planets orbit the Sun?

Like planets, dwarf planets are generally round (Haumea looks like an overinflated football) and orbit the Sun. There are likely thousands of dwarf planets waiting to be discovered beyond Neptune. The five best-known dwarf planets are Ceres, Pluto, Makemake, Haumea, and Eris.
