The above statement puts into perspective the unique nature of space and the universe: It’s mostly empty, a vacuum. The Solar System, which includes all the planets, asteroids, and the Sun, which has a mass of roughly 2.0 x $\10^{30}$ kilograms. Yet, since the Solar System is so large, the density is still quite less than even a gas. https://nathan.freedomland.xyz/posts/getting_started_astrophysics/ Wed, 01 Nov 2023 00:00:00 +0000 https://nathan.freedomland.xyz/posts/getting_started_astrophysics/ Hello everyone and welcome to the starting point of my astronomy and astrophysics series! Space is something I am very passionate about and I’m very excited to giude you through some basic steps of learning about our universe in a scientific way. This post will simply outline some of the material I will cover in this series. What to Expect from this Series: I will start out discussing basic things like computing the force of gravity and finding the distances to the closest stars using a trivial trigonometric method called Parallax.
