During the chaotic era of the solar system, Jupiter may have contributed to the formation of Earth’s moon

by

It seems that the so-called ‘great instability’ event that caused chaos among the planets and the gas giants their journey through space until they settled into the orbits we know today took place between 60 and 100 million years after the birth of the solar system. This is the conclusion of careful scientific detective work … Read more

Earth’s strange ‘quasi-moon’ Kamo’oalewa is a fragment shot from the moon’s large crater

by

Earth’s ‘quasi-moon’ probably rocketed away from the actual moon relatively recently in the solar system’s history, a new study suggests. Kamo’oalewa, a 131- to 328-foot-wide (40 to 100 meters) Near Earth Object (NEO), was liberated between 1 million and 10 million years ago by an asteroid impact, an impact that destroyed the 13.7-mile-wide ( 22 … Read more
