NASA announced Thursday it has discovered a planet that is a “bigger, older cousin” to our planet, which they called a big step toward finding “Earth 2.0” -
2.
The planet, called “Kepler-452b,” was found during NASA’s Kepler mission. Scientists say the planet is unique because it is the smallest planet found so far that is both in the so-called habitable zone and orbits around a sun that is similar to our own. In simpler terms, Kepler-452b and its sun more closely resemble our planet and sun than any other planet NASA has found. -

Kepler-452b is 60% bigger than our planet, and has a slightly longer, 385-day orbit around its sun. It is also older than Earth by about 1.5 billion years. Scientists say they consider the planet to be Earth’s “older, bigger cousin.” “It’s awe-inspiring to consider that this planet has spent 6 billion years in the habitable zone of its star; longer than Earth,” NASA’s Jon Jenkins said. “That’s substantial opportunity for life to arise, should all the necessary ingredients and conditions for life exist on this planet.” -

But if there is another species living on the planet, it will take us a while to reach them. Kepler-452b is 1,400 light-years away from Earth.
