Beyond Pluto

... In the 1940s and 1950s, astronomers Kenneth Edgeworth and Gerard Kuiper independently predicted that a reservoir of icy rocks lay beyond the orbit of Neptune. Many became short-period comets, with orbits of 200 years or less, that blasted in toward the sun, crossing the orbits of most planets. Exclu ...

... 1. How does the elliptical shape of Earth’s orbit affect the seasons? In the critical analysis of an idea, it can be helpful to exaggerate the importance of a single factor. Doing so not only reveals the effect of that factor but can also reveal the inner workings of the process itself. Earth’s orbi ...

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.
