The coldest planet in the solar system is Neptune, which is the eighth and final planet from the sun. Neptune has a minimum temperature of about -218 degrees Celsius (-360 degrees Fahrenheit) and is known for its bluish appearance, which is caused by methane in its atmosphere.
Neptune is a gas giant, like Jupiter, Saturn, and Uranus, and is made up mostly of hydrogen and helium, with a small solid core. It is the fourth largest planet in the solar system and has a diameter of about 49,528 kilometers (30,775 miles).
Despite being the coldest planet, Neptune is also one of the windiest planets in the solar system, with winds that can reach speeds of up to 2,100 kilometers per hour (1,300 miles per hour). It has a system of rings and 13 known moons, and it takes about 164.8 years to orbit the sun.

Neptune was discovered in 1846 and is named after the Roman god of the sea. It is the eighth planet from the sun and is the last planet in the solar system. It is also the most distant planet from the sun and is not visible to the naked eye.
Neptune satellite
Neptune has 13 known moons, the largest of which is Triton. Triton is the seventh largest moon in the solar system and was discovered in 1846, just a few days after Neptune was discovered. It is named after the Greek sea god Triton and is the only large moon in the solar system with a retrograde orbit, meaning that it orbits Neptune in the opposite direction to Neptune’s rotation.
Triton is a frigid, icy world with a surface temperature of about -235 degrees Celsius (-391 degrees Fahrenheit). It is made up mostly of water ice and is thought to have a rocky core. Triton is also one of the few moons in the solar system to have a thin atmosphere, which is composed mostly of nitrogen and methane.
Other moons of Neptune include Nereid, Proteus, Larissa, Despina, Thalassa, Naiad, Galatea, Halimede, Sao, Laomedeia, Psamathe, and Neso. These moons are much smaller than Triton and are thought to be made up mostly of rock and ice.
Planets and solar system
The solar system is the collection of celestial objects that orbit the sun and includes the eight planets and their moons, dwarf planets, asteroids, comets, and other celestial objects.
The eight planets in the solar system, in order from the sun, are:
- Mercury: Mercury is the smallest planet in the solar system and is also the one closest to the sun. It has a rocky, cratered surface and a very thin atmosphere.
- Venus: Venus is the second planet from the sun and is similar in size and composition to Earth. It has a thick, toxic atmosphere and is the hottest planet in the solar system.
- Earth: Earth is the third planet from the sun and is the only known planet to support life. It has a diverse range of environments and is the largest of the terrestrial planets.
- Mars: Mars is the fourth planet from the sun and is known for its reddish appearance, which is caused by iron oxide (rust) on its surface. It has a thin atmosphere and is home to the largest volcano and the longest canyon in the solar system.
- Jupiter: Jupiter is the fifth planet from the sun and is the largest planet in the solar system. It is a gas giant with a diameter of about 142,984 kilometers (88,736 miles) and is known for its beautiful ring system.
- Saturn: Saturn is the sixth planet from the sun and is the second largest planet in the solar system. It is a gas giant with a diameter of about 120
How cold is Neptune?
The temperature on Neptune can vary significantly depending on location, but it is generally quite cold. The average temperature on Neptune is about -200 degrees Celsius (-330 degrees Fahrenheit). This is due to the fact that Neptune is a gas giant planet, and it is located far from the sun, which means that it receives very little heat and light. The outer layers of Neptune’s atmosphere are also very cold, with temperatures ranging from about -220 degrees Celsius (-360 degrees Fahrenheit) to -240 degrees Celsius (-400 degrees Fahrenheit). The temperatures on Neptune’s surface are much colder and can reach as low as -250 degrees Celsius (-418 degrees Fahrenheit).
Hottest and coldest planet in the solar system
The hottest planet in the solar system is Venus, which has an average surface temperature of about 460 degrees Celsius (860 degrees Fahrenheit). Venus is the hottest planet in the solar system because it has the thickest atmosphere, which traps heat and causes the planet’s surface temperature to rise.
The coldest planet in the solar system is Uranus, which has an average surface temperature of about -195 degrees Celsius (-320 degrees Fahrenheit). Uranus is the coldest planet in the solar system because it is a gas giant planet located far from the sun, which means that it receives very little heat and light. The outer layers of Uranus’s atmosphere are also very cold, with temperatures ranging from about -220 degrees Celsius (-360 degrees Fahrenheit) to -240 degrees Celsius (-400 degrees Fahrenheit). The temperatures on Uranus’s surface are much colder and can reach as low as -250 degrees Celsius (-418 degrees Fahrenheit).
