3 days ago · Planet, broadly, any relatively large natural body that revolves in an orbit around the Sun or around some other star and that is not radiating energy from internal nuclear fusion reactions. There are eight planets orbiting the Sun in the solar system.
3 days ago · Solar system - Planets, Moons, Orbits: The eight planets can be divided into two distinct categories on the basis of their densities (mass per unit volume). The four inner, or terrestrial, planets—Mercury, Venus, Earth, and Mars—have rocky compositions and densities greater than 3 grams per cubic cm. (Water has a density of 1 ...
5 days ago · An orbit is a fixed path on which electrons revolve around the nucleus. An orbital is the probable area of finding the maximum density of electrons in an atom. An orbit is a planar representation, i.e., a two dimensional representation. An orbital is a three dimensional representation.
3 days ago · To completely define orbital angular momentum in three dimensions, it is required to know the rate at which the position vector sweeps out angle, the direction perpendicular to the instantaneous plane of angular displacement, and the mass involved, as well as how this mass is distributed in space.
5 days ago · Under the current definition, a planet is a celestial body that orbits the sun, is massive enough that gravity has forced it into a spherical shape, and has cleared away other objects near its orbit around the sun.
3 days ago · Atomic orbitals are wavefunctions describing the probability distribution of an electron orbiting an atom. While it is impossible to know the exact location of an electron at a given time, the orbital can be used to determine the energy of the electron.
