Neptune 🌊 

The 8th and farthest planet in our solar system

Quick Facts

- Type: Ice giant

- Distance from Sun: ∼4.5 billion km / 30 AU. Takes 165 Earth years to orbit once

- Diameter: ∼49,244 km — about 4x wider than Earth

- Day length: 16.1 Earth hours

- Year: 164.8 Earth years

- Moons: 14 known moons. Biggest is _Triton_

- Rings: Yes, faint and dark. 5 main rings

- Color: Deep blue due to methane in the atmosphere

- Temperature: ~-214°C at the cloud tops. Coldest planet in the solar system

What makes Neptune special

1. Windiest planet: Winds can hit 2,100 km/h. That’s faster than the speed of sound on Earth

2. Great Dark Spot: Like Jupiter’s Red Spot, but storms come and go. Voyager 2 saw one in 1989

3. Discovered with math: Scientists predicted Neptune’s position by noticing Uranus’ orbit was being tugged. It was found in 1846 — the only planet found this way

4. Triton is weird: Neptune’s largest moon orbits _backwards_ and has geysers that shoot nitrogen ice. It’s probably a captured Kuiper Belt object

5. It rains diamonds: The extreme pressure may turn methane into diamond rain deep in the atmosphere

Can you see it?

Not with the naked eye from Karachi. You need at least a small telescope. It just looks like a tiny blue dot. 

Best viewing: August-September when it’s opposite the Sun.

Visits

Only 1 spacecraft has flown by: Voyager 2 in August 1989. It gave us almost everything we know about Neptune.
