Earth's closest cosmic companions, known as 'minimoons' or 'quasi-moons', could hold the secrets to the history of our early solar system.

Near-Earth asteroids are similar to time capsules, holding secrets to the early history of the solar system, experts say. Temporary companions called 'minimoons' may be the best place to unearth these secrets.

The solar system has many secrets that researchers are still trying to unravel. They are turning to space rocks that according to evolutionists may unravel to story of how we got here. For instance, NASAs “OSIRIS REx mission discovered water and carbon — two of the precursors for life on Earth — on the 4.5billion-year-old asteroid Bennu.”

According to evolution, ”among the thousands of asteroids swarming near Earth’s orbit, minimoons — tiny cosmic bodies, whose orbits are partially governed by Earth and partially by other solar system bodies — may be prime candidates for learning about the origins of the solar system, said Richard Binzel, a professor of planetary sciences at the Massachusetts Institute of Technology.”

Miniscule objects, such as “Bennu or a minimoon, are "like time capsules," Paul Abell, chief scientist for small body exploration at NASA, told Live Science. "They give us indications of what the early solar system was like [and] what the conditions were."
