The document discusses the planet Neptune, including that it was discovered in 1846, has an average temperature of -360 degrees Fahrenheit, and is composed primarily of hydrogen, helium, and methane. It notes facts like Neptune's winds reaching speeds of 1,490 miles per hour and its orbital period being equivalent to 165 Earth years. The document also explains that while Neptune contains water, its atmosphere is not suitable for human life due to the lack of oxygen.

3. About Neptune
 Orbital period: 60,189 days
 Atmosphere: hydrogen, helium, and methane
ₒ
 Average temperature: -360 F
 Neptune has 13 moons and
6 rings

4. Neptune’s Discovery
 Neptune was discovered by John Couch
Adams in 1846.
 Neptune got its name from the god of
water.
 A spacecraft called Voyager 2 studied
Neptune in 1989.

5. Interesting Facts
 Winds howl across the planet at speeds
up to 1,490 miles.
 Neptune is so far away from the sun that it
takes 165 Earth years to make one orbit.
 Very strong winds push clouds across
Neptune.

6. Living on Neptune
 People could not survive on Neptune
because it does not have oxygen.

7. Water and Gases
 There is water on Neptune.
 Neptune’s core has molten
rock, water, liquid ammonia, and methane.
 Hydrogen, helium, and a small amount of
methane gives the clouds blue color.

8. Neptune and Earth
 Neptune is 2,700,000,000 miles from
Earth.
 Neptune doesn’t have landforms because
it doesn’t have a flat surface.
 A day on Earth is 24 hours; a day on
Neptune is 16 hours and 6 minutes.
 A year on Neptune is 164.79 Earth years.

9. Summary
 Neptune has 6 rings and 13 moons.
 Neptune is so cold because it’s so far
away from the Sun.
 Neptune has water but people can’t live
on it because it doesn’t have oxygen.
