Detailed explanation-1: -Using data from NASA’s Transiting Exoplanet Survey Satellite, scientists have identified an Earth-size world, called TOI 700 e, orbiting within the habitable zone of its star – the range of distances where liquid water could occur on a planet’s surface. The world is 95% Earth’s size and likely rocky.

Detailed explanation-2: -Scientists at NASA have recently announced that they found a planet that is almost identical (about 95%) to Earth’s size and shape and has a rocky surface. Named TOI 700 e, this new planet orbits within its star’s habitable zone, which also hints at the presence of water on its surface.

Detailed explanation-3: -Known as Kepler 452b, the world is estimated to be a bit on the hefty side, at five times the mass of Earth, but it is receiving just 10% more heat and light than we do from its G-type star, just like our sun but 1.5 billion years older.

Detailed explanation-4: -Much of the information about the planets in the solar system has been determined by observation. The planets Venus, Mars, Jupiter and Saturn can all be seen with the naked eye. However much better information can be gathered with a telescope and, better still, by satellite and space probes.
