✪ The Solar System is made up of the Sun and all of the planetary objects that move around it.
✪ Our solar system is a vast place, with lots of mostly empty space between planets. But out there are comets, asteroids and more rocky, frozen objects (including dwarf planets) yet to be discovered in the Kuiper Belt and Oort Cloud. (Credit: Nasa)
✪ Apart from the Sun, the largest members of the Solar System are the eight major planets- Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
✪ Nearest the Sun are four terrestrial planets (also called telluric planets or rocky planets) - Mercury, Venus, Earth and Mars.
✪ Beyond Mars other four are gas giants, mostly made of hydrogen and helium sometimes also known as a Jovian planets after the planet Jupiter, or giant planets - Jupiter, Saturn, Uranus and Neptune.
✪ A belt lies between Mars and Jupiter, called asteroid belt – a region populated by millions of rocky objects.
✪ Disk-shaped Kuiper belt can be find beyond the orbit of Neptune, in which dwarf planet Pluto resides, and far beyond that is the giant, spherical Oort Cloud and the teardrop-shaped heliopause.
✪ Five planets that can be seen without using a telescope are Mercury, Venus, Mars, Jupiter and Saturn. In the sky at night, the planets do not twinkle in the way that stars do.
