Most calendars are based on the Earth's movement round the Sun. The Gregorian calendar is used in most countries and it has 365 days in a year, with an extra day (February 29) in 97 years out of every 400, which are called leap years. This gives an average year of 365.2425 days.

How might earths climates be different if earths were not tilted on its axis?
Earth's climates might be different because they won't be the same
How is the moons orbit around the earth realted to an apple falling from the tree?
the gravitaional pull
What are calendars based off of?
Calendars are based off of the solar system and how the Earth revolves around the sun.
What is responsible for the earths moons phases?

Are you closer to the earths core or moons surface when standing at sea level?
Earth's core
How many moons would fit across the Earth?
4 moons would go across the earth, and 109 earths would go across the sun.
Why is there the moons gravity is only16 of the earths?
The earth has a colossal size more mass
How many moons can fill the circumference of the sun?
Approximately 109 Earths could fit across the sun's diameter, based on the sun being about 109 times wider than Earth. Since the moon is much smaller than Earth, it would take many more moons than Earths to fill the circumference of the sun.

The moon's diameter would fit in the Earth's diameter?
Yes. The moons size is 1/6th of earths so it can fit in the earth.
How much stronger is the earths gravity than the moons gravity?
The moon's gravity is about 1/6th of Earth's.
What are earths moons names?
