Ever wondered what planet has an 88-day orbit? Well, it's the planet Mercury! Mercury is the closest planet to the sun in our solar system, and because of its proximity to the sun, it has a very short year compared to Earth.
Having an 88-day orbit means that Mercury completes one full orbit around the sun in just 88 Earth days. This rapid orbit is due to its close proximity to the sun, which causes Mercury to travel at a faster speed.
Key facts about Mercury’s environment
Here are some interesting facts about Mercury:
- Mercury is the smallest planet in our solar system.
- It has a very thin atmosphere, so temperatures on Mercury can vary drastically between day and night.
- A day on Mercury is longer than its year due to its slow rotation.
