Second “Earth” is found
Scientists use a telescope. This telescope is called the Kepler telescope. It is powerful.
The scientists find a planet with it. The planet is 1,400 light years away. The planet is called Kepler-452. It is 60 per cent bigger than Earth.
The planet moves around a star. This star is like our sun. The planet is at a good distance from the star. There can be liquid water on the planet. Maybe, life exists on the planet.
Difficult words: telescope (a thing for looking at stars and planets), distance (the space between two things; how far something is), liquid (when something is like water—it is not ice and it is not gas).
Scientists used NASA’s powerful Kepler telescope and they found a planet. It is about 60 per cent bigger than Earth, and it is located 1,400 light years away.
The planet is now known as Kepler-452. It circulates a star at a distance which is similar to Earth’s orbit. The planet’s star is similar to the sun. It is only older.
The planet is special because it is cool enough to have liquid water on the surface. Therefore, life could be possible on such a planet.
Difficult words: telescope (a thing which is used for watching the space), orbit (the way which a planet travels around a star), liquid (“normal”; not gas, not ice).

Scientists using NASA’s powerful Kepler telescope have found a planet beyond the solar system that’s a close match to Earth. The planet, which is about 60 per cent bigger than Earth, is located about 1,400 light years away. The latest discovery is known as Kepler-452b.
While similar-sized planets have been found before, Kepler-452b is a circulating star that is very similar but older than the sun at a distance about the same as Earth’s orbit.
Based on its size, mission scientists said they believed it was the most Earthlike planet yet.
Such worlds are of interest to astronomers because they might be small and cool enough to host liquid water on their surface and might therefore be hospitable to life.
The planet is included in a haul of 500 new possible planets sighted by the Kepler space telescope around distant stars.
Difficult words: host (to have), hospitable (friendly), haul (a large discovery)
