(WHTM) – Our solar system has eight (was nine) planets and is roughly 4.571 billion years old.
The planets in our solar system include Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune (Pluto was the ninth before becoming a dwarf planet.)
So of the eight plants in the solar system, which one is the largest and which one is the smallest?
Largest
The largest planet is Jupiter with a radius of 43,440.7 miles and is a gas planet (gas giant).
The planet was formed around 4.5 billion years ago and the gas planet is made up of hydrogen, and helium, and the visible clouds are ammonia, according to NASA.

Jupiter’s days last 10 Earth hours, the planet’s year lasts 12 Earth years, and it is the fifth closest planet to the sun.
Jupiter is also home to “The Great Red Spot” which is an anticyclone. This storm has lasted for over 150 years, according to Space.

Due to being made of gas, Jupiter has no surface, and with the high pressure mixed with the high temperatures, anything that would get near Jupiter’s core would be crushed, melted, or vaporized, according to NASA.
NASA states that the core could reach up to 90,032 degrees Fahrenheit but in the clouds, the temperatures are around negative 145 degrees Fahrenheit.
Jupiter has 95 moons and in 1979, NASA found that the planet has rings that are only visible when they are backlit by the sun.
Smallest
The smallest planet in the solar system is Mercury with a radius is 1,516.0 miles which is slightly larger than Earth’s moon.

According to NASA, Mercury was formed around 4.5 billion years ago and the planet has 88 days in a year.
If you were to walk on Mercury, the surface would resemble the Earth’s moon, but walking on Mercury’s surface wouldn’t be survivable as it can reach up to 800 degrees Fahrenheit.

Mercury has an exosphere and is composed of oxygen, sodium, hydrogen, helium, and potassium, NASA states.
The planet also has no moons.
