Formation and evolution of the Solar System impact event, the Tunguska event, the Chelyabinsk meteor and the impact feature Meteor Crater in Arizona. The process of accretion, therefore, is not complete, and may still pose a threat to life on Earth. Over the course of the Solar System's evolution, comets were ejected out of the inner Solar System by the gravity of the giant planets, and sent thousands of AU outward to form the Oort cloud, a spherical outer swarm of cometary nuclei at the farthest extent of the Sun's gravitational pull. Eventually, after about 800 million years, the gravitational disruption caused by galactic tides, passing stars
Jovian–Plutonian gravitational effect 1980, Moore collaborated with Clyde Tombaugh, the man who had discovered Pluto in 1930, to publish a new book about the dwarf planet. The hoax claims that the gravitational pull of Jupiter and Pluto combined will cause one to spend a significantly longer amount of time in the air due to an increase in gravitational pull from the distant planets; however, this is incorrect. Although other planets do exert a gravitational pull on humans on Earth, the amount is very small. Although Jupiter is very massive, it is also very far away. When at its closest distance to Earth of
