Rotation period

Teach Astronomy - Motion of the Moon

http://www.teachastronomy.com/ We always see the same features on the surface of the Moon.  This means that the Moon's rotational period equals the time that it takes to orbit the Earth.  This is called synchronous rotation.  The time that it takes for one phase of the Moon to recur in the

Teach Astronomy - Solar and Sidereal Day

http://www.teachastronomy.com/ A sidereal day is a period of the Earth's rotation with respect to the celestial sphere, the time it takes for a star to appear at the same angle in the sky from one day to the next. A solar day is a period of the Earth's rotation with respect the Sun, the t

Teach Astronomy - Solar and Lunar Calendars

http://www.teachastronomy.com/ The fundamental issue of calendars comes down to two astronomical numbers. One is the solar year, the time it takes the Earth to go a complete orbit of the Sun, or the time it takes the Sun to reappear at the meridian, at the highest point in the sky from on
