It consisted of six 43 minute episodes, grouped into three chapters of two episodes each. The show was created by Philip Levens and Adrian A ...
Right ascension is usually measured in sidereal hours, minutes and seconds instead of degrees, a result of the method of measuring right ascensions by timing the passage of objects across the meridian as the Earth rotates. There are 360° / 24 h = 15° in one hour of right ascension, and 24 h of right ascension around the entire ...
Right ascension (abbreviated RA; symbol α) is the angular distance of a particular point measured eastward along the celestial equator from the Sun at the March equinox to the (hour circle of the) point in question above the Earth. [1] When paired with declination, these astronomical coordinates specify the location of a point on the celestial ...
For geocentric orbits, Earth's equatorial plane as the reference plane, and the First Point of Aries (FPA) as the origin of longitude. In this case, the longitude is also called the right ascension of the ascending node (RAAN). The angle is measured eastwards (or, as seen from the north, counterclockwise) from the FPA to the node.
They pulled off the first private spacewalk while orbiting nearly 460 miles (740 kilometers) above Earth, higher than the International Space Station and Hubble Space Telescope. Their spacecraft ...

Precessional movement of Earth. Earth rotates (white arrows) once a day around its rotational axis (red); this axis itself rotates slowly (white circle), completing a rotation in approximately 26,000 years [ 1 ] In astronomy, axial precession is a gravity-induced, slow, and continuous change in the orientation of an astronomical body's ...
