12/14/10 – Ephemeris – The bright star Aldebaran
Tuesday, December 14th. The sun will rise at 8:11. It’ll be up for 8 hours and 50 minutes, setting at 5:02. The moon, 1 day past first quarter, will set at 2:20 tomorrow morning.
The central constellation of winter, Orion, is in the southeast at 9 p.m. Above right of it, high in the south is Taurus the bull. The bright orange star in Taurus is Aldebaran. Aldebaran appears at the upper left tip of a letter V group of stars that is the face of the bull. Aldebaran isn’t actually part of the group, called the Hyades star cluster. The cluster is about 151 light years away, while Aldebaran is 65. Aldebaran is heading southward while the Hyades is heading to the northeast. The star has an orange hue because its surface is cooler than the sun’s. However Aldebaran is 44 times larger in diameter, and shines 150 times brighter than the sun. The name Aldebaran means “Follower” because it follows the Pleiades star cluster to its right through the skies.

why is the sun brighter ? today it seems it’s closer to the earth and brighter.
I’m not sure of your question. Yes the sun is closer to the earth now than during the late spring and summer. The difference isn’t much in the way of distance or brightness. Aldebaran, being a red giant is much brighter than the sun. When comparing star brightnesses we talk about the stars absolute brightness or intrinsic luminosity or the star’s brightness at a standard distance.. Were the sun at Aldebaran’s distance, you’d need binoculars to spot it.
thank you sir it seems a little more brighter and the sun looks a little bigger in the sky.
