1. Neptune is the fourth largest planet in the Solar System, with a diameter of about 49,244 km (30,598 miles).
2. It was named after the Roman god of the sea, Neptune.
3. Neptune has the strongest winds in the Solar System, with speeds that can reach up to 2,100 kilometers per hour (1,300 miles per hour).
4. It takes Neptune about 164.8 Earth years to complete one orbit around the Sun.
5. Neptune is the coldest planet in the Solar System, with temperatures that can drop as low as -220 degrees Celsius (-364 degrees Fahrenheit).
6. Neptune has 14 known moons, the largest of which is Triton. Triton is one of the coldest known objects in the Solar System, with a surface temperature of about -235 degrees Celsius (-391 degrees Fahrenheit).
7. Neptune’s atmosphere is primarily composed of hydrogen, helium, and methane gas, which gives the planet its blue color.
8. Neptune was first discovered in 1846 by the French mathematician Urbain Le Verrier, based on mathematical calculations of irregularities in the orbit of Uranus.
9. The Voyager 2 spacecraft is the only spacecraft to have flown by Neptune, in 1989. It provided the most detailed information about the planet and its moons.
10. Neptune’s magnetic field is tilted at an angle of about 47 degrees to its rotational axis, which is one of the most extreme tilts among the planets in the Solar System.
