Oort cloud - Wikipedia

WebThe Oort cloud is a hypothetical object (cloud of many objects) that is proposed as a source of long term comets. Currently, there is absolutely NO empirical evidence that it … WebThe Oort cloud is a hypothesized sphere containing many small Solar System bodies, reaching out to roughly 50,000 AU (astronomical units) or nearly one light-year from the sun. Gravitational forces from passing stars or collisions with other objects sometimes perturb one of these bodies enough to let it fall into the inner solar system. The Oort cloud , sometimes called the Öpik–Oort cloud, first described in 1950 by the Dutch astronomer Jan Oort, is a theoretical concept of a cloud of predominantly icy planetesimals proposed to surround the Sun at distances ranging from 2,000 to 200,000 AU (0.03 to 3.2 light-years). It is divided into two … Ver mais There are two main classes of comet: short-period comets (also called ecliptic comets) and long-period comets (also called nearly isotropic comets). Ecliptic comets have relatively small orbits, below 10 au, and follow the Ver mais The Oort cloud is thought to have developed after the formation of planets from the primordial protoplanetary disc approximately 4.6 billion years ago. The most widely … Ver mais Most of the comets seen close to the Sun seem to have reached their current positions through gravitational perturbation of the Oort cloud by the Ver mais Space probes have yet to reach the area of the Oort cloud. Voyager 1, the fastest and farthest of the interplanetary space probes currently … Ver mais The Oort cloud is thought to occupy a vast space from somewhere between 2,000 and 5,000 au (0.03 and 0.08 ly) to as far as 50,000 au (0.79 ly) from the Sun. Some estimates place the outer boundary at between 100,000 and 200,000 au (1.58 and 3.16 ly). The … Ver mais Comets are thought to have two separate points of origin in the Solar System. Short-period comets (those with orbits of up to 200 years) are generally accepted to have emerged from either the Kuiper belt or the scattered disc, which are two linked flat discs of icy debris … Ver mais Besides the galactic tide, the main trigger for sending comets into the inner Solar System is thought to be interaction between the Sun's … Ver mais homeschool robotics class
