The stars in the tables below have all appeared as a Star of the Week on Skylights. The first two tables list the stars alphabetically by proper name (where available, otherwise by Greek letter name or other designation). The third table arranges the stars by Greek letter name within their parent constellations, which are linked to labelled photographs that show the stars' locations.
STARS now contains:
- 104 constellation photographs plus labelled versions that include:
- 84 of the 88 constellations;
- all but one of the ancient constellations;
- all those of the Zodiac;
- all those of the northern hemisphere;
- the stories of 410 stars (added to by doubles and those in the Planet Project) that include:
- the luminaries of all of the constellations presented;
- all the stars as down to the brightness of Polaris, magnitude 2.02.
Note to readers: The temperatures of the stars are in degrees Kelvin
, which are
centigrade (Celsius) degrees above absolute zero, -273 degrees C (-459 degrees F). Stellar and orbital radii are commonly
given in Astronomical Units
, where the AU is the average distance between the Earth and Sun (technically the semi-major
axis of the Earth's orbit), equal to 150 million kilometers or 93 million miles, or in solar radii, where the solar radius
is 696,000 km (432,000 miles). Stellar distances are in light years
, where the light year is the distance light travels
in one year, equal to 63,270 AU (and 0.3066 parsecs, where the parsec equals 206,265 AU, 3.2616 light years).
