Did you know that Neptune`s first moon was discovered 17 days after the planet was discovered! My space report will be on the planet Neptune. Neptune has a lot of cool things to learn about so let's jump right in!Did you know one day on Neptune is 16 hours and 6 minutes, that surprised me because Neptune`s year is 165 earth years! Wow, we wouldn`t even make it to our first birthday!
Neptune is 4.498 billion km away from the sun. The blue colour comes from the atmosphere; the atmosphere is made out of hydrogen, helium and methane that give Neptune its blue colour. There are 8 planets in the solar system and Neptune is the farthest from the sun, it is 24 622 km in diameter, in diameter it ranks 4th largest and 3rd in mass, it's 17 times bigger than earth! Neptune is the smallest gas giant. The gravity on Neptune is similar to earth's gravity, for example if a 50 pound person was on Neptune they would weigh 60 pounds.
The temperature on Neptune averages at -214 celsius, wow that's colder than the North or South Pole! That's more than 100 degrees colder than earth has ever been. Neptune has 13 satellites (or moons), the most known one is Triton, discovered October 10th 1846, then it's 2. Nereid discovered 1949, 3. Naiad discovered 1989, 4. Thalassa discovered 1989, 5. Despina discovered 1989, 6. Galatea found 1989, 7. Larissa found 1981, 8. Proteus found 1989, 9. Halimede discovered 2002, 10. Psamathe found 2003, 11. Sao discovered 2002, 12. Laomedeia found 2002, and 13. Neso found 2002.
Neptune also has six very thin rings around the planet, they are made of small rocks and dust. If a human were to live on Neptune they would not survive long because of the atmosphere they wouldn't be able to breathe, you would be hurt by the intense winds and the cold temperatures would probably kill you. Also, Did you know that Neptune was named after the god of the sea, Poseidon, because of the planets blue colour! Thank you for reading my space report.
