Was named the Country Vocalist of the Year several times by the Washington Area Music Association and has sung the National Anthem a capella at Camden Yards in front of 49000 people.

. Also nearly overhead toward the North will be the. You may think. Venus magnitude 46 is the bright Morning Star shining low in the southeast during dawn.

Welcome to pre-telescopic astronomy and to techniques of scientific measurement generally. Mars vastly fainter at magnitude 12 continues to hang 4 lower right of Venus all weekLook for it early before dawn gets too bright. Has a deep and abiding love for the music of Buddy Holly.

Arcturus is the 4th brightest star in our night sky and is 367 light-years from us. In addition to establishing a popular annual celebration of Buddys life and music JP. The bright star appearing nearest to overhead will be Pollux the brighter of the twin stars in the constellation Gemini at 75 degrees above the southeastern horizon.

Measure many times and take the midtime between when the center of the Moon last seems just a trace off the Castor-Pollux line and when it first seems just a trace off on the other side. It is not quite twice the mass of our Sun but about 9 times the diameter and 33 times the brightness. With a B-V colour index of 185 Betelgeuse is distinctly red.

This kind of thing done in vast quantities by skilled people using naked-eye tools. Rigel B has a. They are in a very tight circular orbit about 074 AU apart and orbit each other every 104 days.

We use the known distance from the Earth to the Sun. It has 85000 times the luminosity of the Sun and 17 solar masses. It is 787 42 times the Suns luminosity and.

Mg072 are even brighter than 1st Class. Magnitude is equivalent to class. The star and its distinctly red colour have been documented since ancient times.

The Greco-Roman astronomer Ptolemy described Betelgeuse as the bright reddish star on the right shoulder in his Almagest in the 2nd century. The primary component in the system Rigel A is 500 times brighter than Rigel B which is itself a spectroscopic binary star. It is classified as a slightly irregular variable star with its luminosity varying from 003 to 03 magnitudes over 22 25 days.

This Weeks Planet Roundup. Pollux is an orange-tinted star about 34 lightyears from Earth. Most modern astrologers lean to a very small orb mainly based on the magnitude of the star the brighter the star the greater the orb.

Betelgeuse may have been brighter than Rigel Beta Orionis at the time. Mars currently shines with a little less than. You can see a more detailed mathematical explanation on how the distances are calculated in the article on distance but in general we measure these distances at two different times in the year when the Earth is on opposite sides of the Sun at 6-month intervals since the Earth makes one rotation around the Sun in one year.

Mercury Jupiter and Neptune are out of sight in the glare of the Sun. Magnitudes of a negative number eg. Capella Aa and Capella Ab have exhausted their core hydrogen and cooled and expanded moving off the main sequence.

While it has about the same mass as our Sun it is about 26 billion years older and has used up its core hydrogen becoming a red giant about 25 times the size and 170 times the brightness of our Sun.
