WebNov 3, 2024 · The Earth Impact Effects Program, a widely used online calculator for a quick estimation of the impact effects (Collins et al., 2005; 2024), also estimates the effective energy release height Z b. In this case, the height Z b is determined on the basis of a semiempirical model of object destruction (pancake model) describing the transverse ... WebAn impact event is a collision between objects in space. They happen regularly in planetary systems, such as our Solar System. They most often involve small objects, such as asteroids, comets or meteors. These have relatively little impact. When a large object collides with a planet like the Earth, it can have serious effects on the planet.
