km. The surface ares of the whole Earth is 510 million square km, so the area of the Moon compared to Earth is only 7.4%. Our new moon is probably between 1.9 and 3.5 metres across, or roughly the size of a car, making it no match for Earth’s primary moon. Two round balloons (at least 8-inch size, preferably 12-inch size) Full-size men’s basketball (or a beach ball or other ball about 75 cm in circumference) Tennis ball or baseball. The volume of the Moon is 21.9 billion cubic km.
A comparison of the diameters of the Earth and the Moon show the former has as diameter of 12,742 km (7,918 mi) and the latter has a diameter of only 3,476 km (2,160 mi). The moon is a bit more than one-fourth (27 percent) the size of Earth, a much smaller ratio (1:4) than any other planets and their moons. Earth is very dense overall (it is the densest planet in the Solar System), but the Moon is light for its size. Local time for New York. How to Use the Planet Size Comparison Chart. To know how big is the Moon compared to Earth one needs real numbers that measure the size of the Earth and the Moon. Using an assortment of playground and toy balls, students will measure diameter, calculate distance and scale, and build a model of the Earth-Moon system.
Earth and Moon Compared. Earth's moon is the fifth largest moon in the solar system. Difference in Diameters of Earth and Moon.
Click on a planet or the Sun for details on composition, mass, gravity, and number of moons.
This is a good comparison since distance across the US is approximately the size of half the circumference of the moon. 1 391 000 km 109x Earth 333 054x Earth 28x Earth - Gas - - Sun Current Distance. From Sun: From Earth: - 147.615 Mil. Upcoming Events. How about volume? The Moon has approximately 1/4 Earth's diameter, 1/50 Earth's volume, and 1/80 Earth's mass.
