What does the tilt of the earth have to do with why the earth revolves around the sun?
The tilt of the earth is what creates seasons, it’s not directly related to why the earth revolves around the sun. The 23.5 degree tilt of the earth means that its axis is never straight up and down. It’s position in relation to revolutions around the sun determines the seasons. So when it’s summer, in the northern hemisphere for example, that means that Earth’s axis is pointing toward the sun. And when it’s winter, it’s pointing away from the sun. Earth’s revolution around the sun determines its point in space. Because the earth is constantly moving, the view of the night sky changes. That’s why constellations appear to be moving across the sky throughout the year.
