How and when was the Moon formed? “Scientists believe the moon formed during a giant impact about 60-175 million years after the solar system was born. To arrive at this estimate, they can use rocks from Earth.” How was the Moon...
What are the major points of the giant impact theory? “In the mid 1970s, researchers proposed the Giant Impact Hypothesis. The new impact scenario envisioned that at the end of its formation, Earth collided with another planet-sized body. This produced a...
What are the theories of the formation of the Moon? “What is most widely accepted today is the giant-impact theory. It proposes that the Moon formed during a collision between the Earth and another small planet, about the size of Mars....
What is co-formation theory? “A co-formation theory proposed that the Earth and. moon formed contemporaneously as a gravitationally bound pair. The third. theory suggested that the moon formed as an independent planetary body that. was later “captured” by the Earth during...
What is the Moon relative to the Earth? “The Moon is Earth’s only natural satellite. It goes around the Earth at a distance of about 239,000 miles (385,000 kilometers).” In what way is the Moon similar to the Earth? “Both are...
Why was the fission theory not accepted? “Fission theory–A molten Earth budded off the Moon. This theory failed because it would imply: a ring of smaller moons rather than one big one. the moons would fly off and then fall back...
What was the Earth like before the Moon? “The Earth formed over 4.6 billion years ago out of a mixture of dust and gas around the young sun. It grew larger thanks to countless collisions between dust particles, asteroids, and other...
How many Plutos could fit in the Sun? “Pluto has a diameter of around 2.376 km / 1.476 mi and a radius of around 1,188 km / 738 mi. It’s not quite a massive planet, since it has only 0.01 Earth...
How many Earths can fit into Neptune? “Neptune is the fourth largest planet in our Solar System and it is the smallest of the giant gas planets. Neptune has a diameter of 34,503 miles (55,528) kilometers. Its volume is 57.7 times...
How many Jupiters can fit inside Sun? “According to multiple studies, around 1,000 Jupiters could fit into the Sun. This calculation was done using the volume of the Sun compared to the…” How many moons can fit inside Jupiter? “That’s pretty...
