solar escape velocity
1Escape velocity — In physics, escape velocity is the speed where the kinetic energy of an object is equal to the magnitude of its gravitational potential energy, as calculated by the equation,:U g = frac{ Gm 1m 2}{r}.It is commonly described as the speed needed to …
2Solar wind — For other uses, see Solar wind (disambiguation). The solar wind is a stream of charged particles ejected from the upper atmosphere of the Sun. It mostly consists of electrons and protons with energies usually between 1.5 and 10 keV. The stream of …
3solar wind — noun The outflow of charged particles from the solar corona into space. Because of the high temperature of the particles of the corona, they are moving at speeds higher than the solar escape velocity …
4Escape from Jupiter — is an Australian children s science fiction drama which aired from April 10, 1994 to July 3, 1994. Concerning a small group of children on Jupiter s moon Io, the series ran for 12 episodes.When one of Io s volcanoes erupts, the group must flee… …
5Solar sail — Solar sails (also called light sails or photon sails, especially when they use light sources other than the Sun) are a proposed form of spacecraft propulsion using large membrane mirrors. Radiation pressure is about 10 5 Pa at Earth s distance… …
6solar wind — an emanation from the sun s corona consisting of a flow of charged particles, mainly electrons and protons, that interacts with the magnetic field of the earth and other planetary bodies. [1955 60] * * * Flux of particles, chiefly protons,… …
7solar system — the sun together with all the planets and other bodies that revolve around it. [1695 1705] * * * The Sun, its planets, and the small bodies (see asteroid, Centaur object, comet, Kuiper belt, meteorite, and Oort cloud) interplanetary dust and gas… …
8Solar Electric Engine — Ionized atoms, such as cesium atoms, are accelerated to high velocity in an electrostatic field, and allowed to escape from the rear of the engine. This type of engine can reach high velocity. In 1998 a satellite using an Ion Engine was… …

9Atmospheric escape — There are several different processes that can lead to the escape of a planetary atmosphere. In some cases this can be a very important process; for example, both Venus and Mars have probably lost much of their water due to atmospheric escape… …
