[00:00:00]planet's albedo, not libido, albedo.

[00:00:02]Have you ever heard of that term?

[00:00:05]>> So, this is the amount of light, or I should say energy, the planet is reflecting. So, very icy objects like Europa would have a very It's from zero to one. Would have like a nearing, let's say, 0.9 albedos. I shouldn't say libido. Earth's is pretty low. It's like 0.3. Yeah. Which means that we are absorb absorb a lot of heat.

[00:00:23]>> And And then that determines also the warmth and therefore viability for life of a planet. So, there's all these factors. I just found that so fascinating. You find a star, you do the methods, and then that allows you to find the radius of a planet. You do another method, you understand its orbit, then its mass by its influence on its star, and then its density, and then And so, you have to go through all these parameters just to see if the planet potentially could be habitable.

[00:00:50]>> Okay.
