descriptive text

Kepler 452 is a sun-like star that wanders through the cosmos 1,400 light-years from Earth. It has the same surface temperature as our sun and nearly the exact same energy output. Ultimately, both the sun and Kepler 452 are G type yellow dwarfs. This means that Kepler 452’s habitability zone (the area surrounding a star in which liquid water could theoretically exist) is nearly identical to the sun’s.

The exact nature of the planet is not known specifically, but Nasa's modelling suggesters it is a rocky planet.
It has about five times as massive as Earth, orbiting its star once every 385 days.

The planet's star is 1.5 billion years older than our own, and is now growing hotter and brighter -- as our star will do in about a billion years.

Kepler-186f is only 10 per cent larger than Earth, but scientists have not yet discovered what the planet is made of – the best theories suggest it has a rocky composition and could supportlife.
