Definition: Schofield net is a term used in astrophysics that describes an object falling toward the Sun as it approaches its final orbit. The term was coined by Carl Sagan in his book "The Hitchhiker's Guide to the Galaxy" (1978). The key point of this concept is that, as an object descends, it experiences a gravitational pull from the Sun, which tends to counteract the acceleration due to gravity. This process results in a net upward movement toward Earth, often referred to as "schofield net."
