correction (Question: 196685.0 )

option A is right

Question:

The term 'Super Earth' in the context of astronomy is –

Options:
A)

a planet outside the solar system with a mass higher than earth.

B)

an experimental space station mimicking the habitable conditions on earth.

C)

a planet outside the solar system with habitable conditions.

D)

a term used for Venus because of its similarity with earth.

Solution:

Ans: (b)

A super-Earth is an extrasolar plant with a mass higher than Earth's, but substantially below the mass of the Solar System's ice giants Uranus and Neptune, which are 15 and 17 Earth masses respectively.

The term super-Earth refers only to the mass of the planet, and does not imply anything about the surface conditions or habitability.

Recently, a new planetary system that includes three super-Earths and one outer giant planet has been discovered by astronomers at a distance of just 21 light years from Earth.
