According to a new study, a meteorite that landed on the roof of a house in Novato, California in October of 2012, might be part of an asteroid that was hit by the moon forming impact over four billion years ago.

According to a new study, a meteorite that landed on the roof of a house in Novato, California in October of 2012, might be part of an asteroid that was hit by the moon forming impact over four billion years ago.

The meteorite was discovered by local woman Lisa Webber after she heard about the meteor shower in the news, and thought of the loud bump on her roof that happened the same night.

Results of the study show that the meteorite started on its course to hit the woman’s roof around the same time that the moon was forming.

Chemical analysis appears to match other asteroids from the Gefion family situated between Mars and Jupiter and according to a researcher may have broken off "from one of the Gefion family asteroids nine million years ago".

Qing-zhu Yin, a professor from the Department of Earth and Planetary Sciences at the University of California, Davis is quoted as saying: “We now suspect that the moon-forming impact may have scattered debris all over the solar system and hit the parent body of the Novato meteorite.”

The Novato meteorite reportedly broke apart as it entered the Earth’s atmosphere, and so far six fragments have been recovered.

Estimates say that the rock was probably around 14 inches long, weighing about 176 pounds when it began to enter our planet’s atmosphere.
