Question
Before the formation of earth’s moon, the young Earth had a twin planet about the size of Mercury. (True or false)
Expert Solution
Step 1
The huge impact hypothesis, which is widely accepted by scientists, claims that the moon was formed when an object collided with early Earth. Earth, like the other planets, arose from a smouldering cloud of dust and gas around a newborn sun. The early solar system was a tumultuous place, and many bodies were formed that never progressed to planetary status. One of these could have collided with Earth not long after it was born.
Theia is a hypothetical old planet in the early Solar System that collided with the early Earth some 4.5 billion years ago, with some of the expelled material forming the Moon, according to the giant-impact hypothesis.
