ELI5: Explain Like I'm 5

Karl Ramsayer

Karl Ramsayer was a smart man who studied the stars and planets in space. He wanted to figure out how they move around and what they are made of. He worked really hard and wrote many books that helped other people learn about space too. He also taught at a university to help students become smart like him. Even though he passed away a long time ago, people still remember him and the important things he did to help us understand the universe.
