... The Round Earth . ... Aristarchus around 270 BC derived the Moon's distance from the duration of a lunar eclipse (Hipparchus later found an independent method). ... Let R be the radius of that circle and T the time it takes the Moon to go around once, about one month. ... Viewed from Earth, a "new Moon" (occuring between the time a thin crescent is last seen before sunrise and the time one is seen shortly after sunset) happens when the Moon in its apparent motion around the sky overtakes the Sun. ...

. Mars is "behind" the sun from the earth's point of view and is therefore not visible in the nighttime sky (i.e. its up in the daytime). Venus it at greatest elongation and appears in the western sky as a bright object for 2-3 hours after sunset .

... Note that in the low-mass model, the ``secondary'' is more massive than the visible ``primary''; however, we shall follow the convention used in most of the Aurig? literature and continue to refer to the F star as the primary because it is clearly the primary source of luminosity of the system. Doppler shifts of absorption lines seen during eclipse imply an orbital velocity at the edge of the secondary more compatible with the low-mass model (Saito et al. ...
