If you could time travel back to the Jurassic period when Dinosaurs existed and looked up at the moon on a clear night it would appear 4 times larger in the sky than it does now due to it being closer to the Earth at that time in Earths history.

The bigger the thing, the more it should be attracted to the planet (big-G), but the spin pushes it away more...so it balances out as little-g. Always. This is why when you drop a penny and a bowling ball from top of leaning tower of Pizza (or whatever Galileo dropped), they hit the ground at same time. Same experiment on the moon gives different results (no spin there).

Gravitational attraction between planets, planets & stars, planets & moons, etc. This is called G (aka big-G). There is force between you and the planet (G) but your mass is very small (despite what you see in the mirror). But it is there. The Earth is spinning (bet you did know that!).

The reason they fall at the same rate as lighter things is that rate of acceleration is proportional to mass (F=MA). The heavier something is, the more force it takes to move it. So gravity exerts a larger force, but the larger mass balances it out and we end up with the same acceleration, g.
Fourier wrote: » The ratio is often named the golden ratio and is around 1.618. Just as pi often pops up if there is a circle present somewhere (often its not obvious immediately where in the situation the circle is), the golden ratio often pops up in places where a certain kind of ellipse shows up (again it is not always obvious there is an ellipse involved). However its frequency is often over stated, it doesn't really show up in the Pyramids, the Parthenon or Renaissance paintings as is often claimed, nor in astrophysics. Some articles for example say it shows up in black holes and the orbits of planets, but this isn't really true. It does show up in flowers, essentially because they are building an ellipse with their petals.

2,730,000 is the circumference of the Sun in miles. Sun Synodic Period: 27.2753 days.

What does it matter for the Sun that two properties of it have "27" in front when measured in particular units. Sure switch to kilometers and one isn't valid, change to a day on Venus and it isn't either. There is an intricate set of mathematical properties to the world, but they're not as simple as just numbers.

If you are Scottish that means it's Hogmanay most of the time.Humans are very good at finding patterns where none exist. Johannes Kepler had a book abou how the orbits of planets matched the sizes of Platonic Solids , think cubes and other dice shape. Later on with better observations and maths he came up a better model. Today we still use Kepler's laws of planetary motion.
