Comet Siding Spring Skimming Mars and Giving Our Satellites a Scare. Here’s Why You Should Be Watching this Event Today!
Comets are fascinating and valuable to astronomers and scientists alike. It helps us understand where we come from or how we even got here. It’s said that comets were the reason water is even on Earth. Now why the fuss over Comet Siding Spring? Well here is the lowdown:
Quick Facts You Need to Know About Comet Siding Spring:
- It will just skim Mars by 87,000 km. To give you an idea, our Moon is about 384,400 km from our Earth so this comet would pass in between earth and the moon and show up like a second sun in the sky.
- Comet Siding Spring is hurtling through space at about 56 km/s!
- The weight alone is about the weight of a mountain. It’s also shedding 220 pounds of dust per second.
- This comet took an estimated million years to come from the Oort cloud. The Oort cloud is 50,000 AU (distance from Sun to Earth is 1 AU) out, hugging our solar system within it.
- It’s passing by so close that our billion dollars worth of satellites need to hide behind Mars so it won’t get annihilated.
Why Should We Care?
Comets come from two places: Oort Cloud and Kuiper belt (50 AU out). The comet is comprised of material that gives us very strong clues of how our solar system formed. We know how the outer planets are formed but still don’t fully understand the inner planets. Comets, especially from the Oort Cloud, are extremely unpredictable and hard to study and don’t come around often. So this gives humans an exciting chance to get a better look at one.
Are We in Danger?
No we aren’t but our billion dollar satellites orbiting #Mars are and scientists had to calculate the exact time for the satellites to hide behind the planet Mars so it won’t get destroyed.
