i)                   The mass of the sun is 1.989 x 1030 kg that is 333,000 times the mass of the Earth. Sun has 99% mass of the entire solar system.

ii)                All the space is completely silent, so one can live there without any noise, though it’s not possible.

iii)              More energy from the sun hits Earth every hour than the planet uses in a year.

iv)              One Million Earths can fit into the Sun. Sun is really big.

Galaxies come in different shapes and different sizes.
Mars is the 4th planet from the sun.
The circle that a planet makes around the sun is called a revolution.
Comets are like the snowballs of space. The consist of frozen water and gas, and also dust and rock.
A day on Mercury equals 60 days on earth.
There are at least two lunar eclipses every year.
A blue moon is the second full moon in a month. It's rare, hence the expression 'once in a blue moon'.
The Haley comet is the earliest recorded comet (I remember when it passed by the earth).
Mars is the second smallest planet in our solar system.
Titan is the name of the biggest moon that is orbiting Saturn.

The life spam of a star depends on how much fuel it has.
The color of a star depends on its temperature.

Proxima Centauri is the star that is nearest to earth (not counting the sun of course), but it's still 4.2 lightyears away from us.
The moon does not have a dark side.
