Scientists have discovered the most Earth-like exoplanet. The exoplanet is Kepler-452b.

It is located in the habitable zone of a star like our sun. Kepler-452b is the first exoplanet orbiting a star that is nearly the same size and temperature as the Sun. It orbits at practically the same distance from its star as Earth does from our sun. Kepler-452b receives just 10 percent more solar energy than Earth, since its host star is older than the Sun. Kepler-452b is slightly hotter than Earth.The planet’s host star is about 1.5 billion years older than the 4.5-billion-year-old Sun.

Kepler-452b has been in the habitable zone for around six billion years. Meaning Kepler-452b much older than Earth.

Kepler-452b orbits around its host star once every 385 days; close to Earth’s 365-day year. The similarities are uncanny. 

Kepler-452b is approximately 60 percent wider than Earth. It’s considered a super-Earth. The distance between Earth and Kepler-452b is 1,400 light years. 




Conditions on Kepler-452b could be like circumstances here on Earth. Scientists don’t know if Kepler-452b is a rocky planet, but it’s most likely a rocky planet. It is likely that Kepler-452b will hold on to any oceans it may have for a longer period. Scientists also believe it could have a thick cloud cover and very active volcanoes. Do you think we’ll be living on Kepler-452b in the future?

Exoplanet: An exoplanet is simply a planet that orbits another star. 

Habitable zone: That’s the area around a star in which water has the potential to be liquid. The planet isn’t so close to the star that all water would evaporate, and not so far that all water would freeze.
