Hace 23 horas · Asteroid mining is the hypothetical extraction of materials from asteroids and other minor planets, including near-Earth objects. [1] Notable asteroid mining challenges include the high cost of spaceflight , unreliable identification of asteroids which are suitable for mining, and the challenges of extracting usable material in a ...
Hace 3 días · The dashboard displays the next five Earth approaches to within 4.6 million miles (7.5 million kilometers or 19.5 times the distance to the moon); an object larger than about 150 meters that can approach the Earth to within this distance is termed a potentially hazardous object. The average distance between Earth and the moon is about 239,000 ...
Hace 3 días · An impact event is a collision between astronomical objects causing measurable effects. [1] Impact events have been found to regularly occur in planetary systems, though the most frequent involve asteroids, comets or meteoroids and have minimal effect.

Hace 4 días · Description. The Double Asteroid Redirection Test (DART) mission is designed to evaluate the kinetic impact technique by striking an asteroid with a spacecraft at high relative velocity and observing the resulting change in orbit.
Hace 1 día · For example, the close approach to Earth of asteroid (99942) Apophis in 2029 will be a very rare event (this case will only appear in the list of upcoming close approaches since April 2028). The formulation associated to the computation of this close approach index can be found here . 1 au = 149597870.7 km. 1 LD = 384399 km.
Hace 2 días · The mission was the first-ever to orbit an asteroid and to touch down on the surface of an asteroid. The primary scientific objectives of NEAR were to return data on the bulk properties, composition, mineralogy, morphology, internal mass distribution and magnetic field of Eros.
