To find the distance between the Earth and Moon you would use Lunar distance. Lunar distance is the measurement from and to the Earth and Moon which calculates 238,900 miles
Find the distance from the earth to the moon, then the the distance from the earth to the sun, and simply subtract the both.
The Sun is at a mean distance of about 150 million kilometers from Earth. The Moon is at a mean distance of 380,000 kilometers from Earth. The direction at which you find them vary over time.
The average distance between the Moon and Earth is about 238,855 miles (384,400 kilometers). This distance can vary due to the elliptical shape of the Moon's orbit. Scientists use radar ranging and laser ranging techniques to precisely measure this distance.
Given the ratio of the distance between the earth to the sun and the earth to the moon, calculations find an incredibly small number, almost 1/400. Multiplying by 400 meters gives a distance of just over 1.028 meters in this comparison.
Moon phases. As the moon revolves around the earth on its tilted path, (search for diagrams to find out what happens with it tilted) the light from the sun hits the moon and reflects towards earth. But we see a different amount of light and darkness depending on where it is in the orbit. This causes us to see different shapes.
The distance from the center of the Earth to the center of the moon is about 384,467 km. If you subtract from this distance the average radius of the Earth (6,378 km) and the average radius of the moon (1,738 km), you find 376,351 km.Convert the diameter of a strawberry seed, 2 millimeters, to kilometers: .000002 km. Now, divide the distance from the surface of the Earth to the surface of the moon by the diameter of a strawberry seed. The answer is: 188,175,500,000 strawberry seeds!
You don't need a mathematical equation. All you need are the numbers.In round, approximate numbers:-- Earth diameter = 12,750 km-- Moon diameter = 3,475 kmIf you want a 'ratio' to amaze your friends with, then you can use an actualmathematical equation for that:The ratio of the Earth's diameter to the Moon's diameter isDE / DM = 3.669 (rounded)-- The linear dimensions of the Earth are 3.669 times as large as those of the moon.By simple geometry, then, you can say that . . .-- the Earth's surface area is 13.462 times that of the moon,-- Earth's volume is 49.39 times the Moon's volume.(If you're in the league of those that are comfortable with mathematical equationsand like to toss them around, then you find that some consider the phrase "timessmaller" to be quite arbitrary, while to others, it has no meaning at all.)
You would find this on the Earth's moon.
From geometry it is known that the circumference of a circle is 2*pi*r - where r is the radius. Assuming the orbit of the moon is a circle, then the distance traveled in one orbit is the circumference of the circle.
The distance from the Earth to the Moon is approximately 384,400 kilometers. If an astronaut travels to the Moon and back in 144 hours, the total distance would be around 768,800 kilometers. To find the average speed, divide the total distance by the total time: 768,800 km / 144 hours, which equals about 5,347 kilometers per hour.
The rotation of the Earth causes us to see the moon differently. When the moon is between the Earth and the sun, there is no light reflecting from the moon, and that is when there is a new moon.
