The Hottest and Coldest Planets in the Solar system

Solar system

Our solar system contains 8 planets, 2 dwarf planets (known worldwide), 575 natural satellites, 796354 known asteroids, and 4143 known comets.

All elements of the solar system revolve around a star orbiting the sun. Our solar system is believed to be 4.568 billion years old. The 8 major planets are classified as giant planets and terrestrial planets. Giant planets are made of gas or ice. On the other hand, the planets are made of rocks.

The following is a list of the warmest and coldest planets and their surface temperatures.

Planet Surface temperature (in degree Celsius)
Venus 462
Mercury -173 to 427
Earth -88 to 58
Mars – 87 to -5
Jupiter -108
Saturn -139
Uranus -197
Neptune -201

Venus, the hottest planet in the solar system, is the second planet from the Sun. Galileo Galilei was the first astronomer to observe the planet with this telescope and record its findings. The planet is named after the Greek goddess Aphrodite and the Roman goddess Venus because it is the brightest celestial body in the sky. It glows very brightly as it absorbs almost 70% of sunlight. Venus has a retrograde rotation, i.e. it moves clockwise from east to west. One fact about Venus is that day and night temperatures are the same.

Mercury, the closest planet to the Sun, can be seen from Earth without the use of a telescope. Galileo Galilei was the first to observe this planet through a telescope. Mercury travels at a speed of about 47 kilometers per second. The surface of this planet is very similar to the surface of the Moon, the natural satellite of the Earth.

Earth is the fifth-largest planet in the solar system and the third-warmest planet. It is the only planet in the Solar System where life is observed. The name Earth is derived from the Greek word “Kia,” meaning terra matter. The name is also believed to have been inspired by the Roman word for fertile soil – “Dallas.”

It is believed that there was once water on Mars, named after the Greek god of war. A few astronomers believe that there is still water on this planet. The planet has a dense core made up of traces of iron, nickel, and sulfur. Craters, plains, and volcanoes have been found on the Great Surface.

5. Jupiter

The hottest and coldest planet in the solar system (2)

  • Structure: Gas Giant
  • Distance from Sun: 5.2 AU (astronomical units)

Jupiter is the fifth warmest and fifth planet from the Sun. Although it is far from the central star, its day is only 10 hours. This means that one day on Earth maybe two and a half days on Jupiter.

The planet’s magnetic field is 20 times stronger than Earth’s. Jupiter’s size is equal to 1,321 Earths.

Saturn is also known as the ring planet because it has more than 30 rings. You can see up to 3 rings in a normal telescope and up to 8 rings in a powerful telescope. This planet takes about 30 Earth years to orbit the Sun. But it will rotate on its axis in 10.6 hours. Saturn’s moon, Titan is larger than Mercury. This planet weighs 95 times as much as Earth.

This massive ice giant planet has 14 known natural satellites and the fastest wind speeds of all the planets. The first record of the planet was made on September 23, 1846, by astronomers Arbine Jean-Joseph Le Warrier and Johan Cole. Its moon, Triton, is the only natural satellite with a backward orbit.

The bright lights in the distant sky always captivated our curiosity and captivated our imagination.

Since ancient times, astronomers have been searching for the infinite expansion of the universe to learn more about what is in it and how it came to be.
