Welcome and is there life around my birthstar?

Obligatory first post, you know this one is going to be fascinating, a chance for me to point to all of the places you can already find by using the menu on the site. Redundancy for victory!

Okay so no, I'm not going to do that. Instead I'm going to talk about my current birthstar, a concept I made up because I was bored. A birthstar is the star whose light has (from the perspective of the featherless, broad flat nailed, bipedal meatsacks of Earth) travelled approximately the same amount of time as you have been alive. So everyone starts off with Sol (the Sun), then very briefly has Proxima Centauri and so on. Code to calculate your birthstar is on this site under code.

As of today I am 32.7, and my current birthstar is Gl 49 (that is entry 49 in the Gliese database. It has an apparent magnitude of 9.56. That means if you want to see light from this star you are going to need to head somewhere pretty rural and grab a very good pair of binoculars.

The details on this star are pretty limited, as is true for a lot of stars. There are a few hundred billion of them in our galaxy so just counting them would take thousands of years, never mind turning a telescope on them and taking careful and detailed recordings.

What we do know about this star, besides where it is, is that it has a K5V spectral type. What this means is it is orange in colour, a bit less massive than the Sun and a bit cooler too, surface temperature ~4000-5000K instead of ~5800K. This makes it an ideal candidate for searches for habitable planets. Smaller orange stars put out less harmful radiation and have a decent habitable zone.

Who knows, maybe 33 light years away there are some 33 year old aliens looking up at the sky and discussing if there is a habitable planet around that obscure little yellow dot in the distance whose light took as long to reach that point in space as they did. Probably not.
