Supermoon happens when the moon on its elliptical orbit is at its closest point to Earth.
So, we will see it bigger than usual.
The moon can appears to be up to 14% larger and 30% brighter than when the moon is at its farthest point, or apogee.
There used to be 9 planets and more than 170 moons in our solar system.
The 9 planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto.
But in August 2006, the International Astronomical Union decided to re-classify Pluto as a “dwarf planet”, and not in the same category as the 8 planets.
So now there are 8 planets in the solar system.
Each planet goes around the Sun on its own path called orbit.
Anyway we cannot see the paths because they are invisible.
Earth takes about 365 days to orbit the Sun.
This is called one Earth year.
And each moons moves around its planet in its own orbit.
The size of the planet from the smallest to the biggest:
People travel to space in a spacecraft or spaceship.
