• Visible in Southern Hemisphere
• Multiple Star System: Alpha Centauri A and B with an extra star, Proxima Centauri, orbiting around.
• Proxima Centauri hangs out with αCen A&B but Proxima is more of a 3rd wheel in the relationship.
• α Cen A: Only slightly larger and brighter than Sol. G2 - Same classification as the sun.
• α Cen B: Slightly smaller and less bright than Sol. K1 classification.
• α Cen C: M5 Red Dwarf.
• Has a known earth-sized planet in the system named Alpha Centauri Bb and likely many others we haven’t seen yet.
Why is Alpha Centauri so cool?
• It’s nearby. It’s the closest system to our own, only 4.37 light years away.
• The stars are really similar to our own star, α Cen A is almost like the suns relative….they’re super similar. Like a long lost sibling that just happens to live 25,600,000,000 miles away. That’s at least as far away as Russia from the US. At least. ;)
• It’s got an Earth sized planet! So basically it’s close by with a similar looking planet with some similar looking stars. Many people think it’d be a good place to look for life.
• Even if life isn’t on this planet we know about, it’s very likely there are more life harboring planets there.
It’s so close, why aren’t we going there?
• 4.6 light years is incredibly close…if you’re traveling at the speed of light. With our conventional technology, it could take up to 200,000 years to get there. 200,000 years ago, our species (modern humans) was just starting to appear. Who knows if we’ll even exist in that time frame.
•We need to be able to travel at least 1/10th the speed of light to get there in a lifetime. That’s nearly impossible with our current infrastructure, we’d need to be able refuel along the way or find a better way to travel.
Random Weird Fact
• Alien enthusiasts believes that Aliens from this system visit us frequently and communicate with our top scientists. Apparently they’re not hostile nor does their diet consist of humans so that’s comforting. According to these people you better hope if you get abducted they’re alpha centaurian. Instead of anally probing you, they’ll just educate the shit out of you.
