Because of the time lag between the first and second transits, a certain plateau appears in light curves. The other ...

... Satellites in low Earth orbits must accurately conserve their orbital eccentricity, since a decrease in perigee of only 5–10% would cause them to crash. However, these satellites are subject to gravitational perturbations from the Earth’s multipole moments, the Moon, and the Sun that are not spheric ...

Astronomical unit

The astronomical unit (symbol au, AU or ua) is a unit of length, roughly the distance from the Earth to the Sun. However, that distance varies as the Earth orbits the Sun, from a maximum (aphelion) to a minimum (perihelion) and back again once a year. Originally conceived as the average of Earth's aphelion and perihelion, it is now defined as exactly 7011149597870700000♠149597870700 meters (about 150 million kilometers, or 93 million miles). The astronomical unit is used primarily as a convenient yardstick for measuring distances within the Solar System or around other stars. However, it is also a fundamental component in the definition of another unit of astronomical length, the parsec.
