Question

Which of the following is the hottest planet of the solar system?
${\text{A}}{\text{.}}$ Mercury
${\text{B}}{\text{.}}$ Pluto
${\text{C}}{\text{.}}$ Jupiter
${\text{D}}{\text{.}}$ Venus

Answer 1

Hint: Here, we will proceed by discussing what is contained by the solar system. Then, we will write down the order in which planets are present in the solar system and then, we will be discussing some facts about the planets mentioned in the options.

Complete step-by-step answer:
The solar system consists of the Sun; the eight official planets, at least three “dwarf planets”, more than 130 satellites of the planets, a large number of small bodies (the comets and asteroids), and the interplanetary medium.
The inner solar system contains the Sun, Mercury, Venus, Earth and Mars. The main asteroid belt lies between the orbits of Mars and Jupiter. The planets of the outer solar system are Jupiter, Saturn, Uranus, Neptune and Pluto. This is the order of the planets in the solar system.
Mercury- The smallest and fastest planet. Mercury is the closest planet to the Sun and whips around it every 88 Earth days. The average temperature of Mercury is usually 430 degree celsius during the day and -180 degree celsius during the night.
Pluto- Pluto will always be the ninth planet which is smaller than Earth’s moon. Pluto was a planet up until 2006 and has five of its own moons. The average temperature of Pluto is -233 degree celsius.
Jupiter- Jupiter is a massive planet, twice the size of all other planets combined and has a centuries-old storm that is bigger than Earth. The average temperature of Jupiter is -108 degree celsius.
Venus- Spinning in the opposite direction to most planets. Venus is the hottest planet, and one of the brightest objects in the sky. The average temperature of Venus is 471 degree celsius.
Planet Venus is similar in structure and size to Earth, Venus spins slowly in the opposite direction from most planets. Its thick atmosphere traps heat in a runaway greenhouse effect, making it the hottest planet in our solar system with surface temperatures hot enough to melt lead.
Therefore, the hottest planet of the solar system is Venus having an average temperature of 471 degree celsius.
Hence, option D is correct.

Note:Earth is the third planet from the Sun and the fifth largest planet in the Solar System with the highest density. It is currently the only known location where life is present. Earth has only one satellite which is the Moon and a couple of temporal artificial satellites. Around 71 percent of the Earth’s surface is covered by water and 29 percent by land.
