Scientists have proposed a spacecraft that could prevent an asteroid from colliding with the Earth.
A small spacecraft with a solar sail placed in a retrograde orbit could change the path of a large asteroid if it collides with it far enough in advance. The project was devised as an answer to the possible threat of the massive asteroid Apophis which is thought to have a small chance of hitting the planet in 2036.
Shengping Gong, Junfeng Li, and Xiangyuan Zeng of Tsinghua University in Beijing, China, have published an article in Research in Astronomy and Astrophysics (RAA), proposing to place a small spacecraft with a solar sail into a retrograde orbit to prevent an asteroid from colliding with the Earth in 2036.
