Question

Name the hottest and coldest planet in the solar system.

Answer 1

Step1: Solar system

1. The solar system consists of the sun and everything that orbits around it.
2. It includes all eight planets and their moons as well as many asteroids and comets.
3. These objects all revolve in orbit around the sun by the sun's strong gravity.
4. Our solar system is made up of a star namely the Sun, eight planets, $146$ moons, a bunch of comets, asteroids and space rocks, ice, and several small planets, such as Pluto.
5. The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune in their increasing distance from the sun respectively.

Step2: Hottest planet

1. Venus is the hottest planet of all eight planets.
2. Its atmosphere is full of carbon dioxide and clouds made of sulfuric acid.
3. The atmosphere confines heat and keeps the planet very warm.
4. The temperature on Venus’s surface can reach up to $880$ degrees Fahrenheit.

Step3: Coldest planet

1. Uranus is the coldest planet in all the eight planets.
2. Most of its mass is a hot, very dense fluid of icy materials like water, methane and ammonia above a small rocky core.
3. Uranus is an ice giant. It holds the record for the coldest temperature ever measured in the Solar System about $-224°C$.

Thus, Venus and Uranus are the hottest and coldest planets respectively.
