Solar system
Why it is night, why summer is hot, and how Chandrayaan reached the Moon.
What is inside
- The Sun. A star: a giant ball of glowing gas that gives every planet its light and warmth.
- Rocky planets. Mercury, Venus and Mars: small, rocky worlds near the Sun.
- Earth & Moon. Our planet, tilted and spinning, with the Moon going round it once a month.
- Asteroid belt. Millions of rocks between Mars and Jupiter — leftovers from when the planets formed.
- Gas giants. Jupiter and Saturn: huge planets made mostly of gas, with no ground to stand on.
- Ice giants. Uranus and Neptune: cold blue worlds at the edge of the planets.
- ISRO’s missions. Chandrayaan to the Moon, Mangalyaan to Mars, Aditya to watch the Sun.
