What does Right Ascension mean?
Right ascension is essentially the longitude on a star chart where you may look to find something in the sky among the stars. The distance of a point east of the First Point of Aries, measured along the celestial equator and expressed in hours, minutes, and seconds.
How much does the right ascension of Betelgeuse change from midnight to 6am?
It doesnt change. The RA is related to the mm/dd/yy by a factor of pi/6. Consider this from Oct21 to Dec21 when Orion is rising in the east. Good Luck..
What is a stars location determined by?
Astronomers use the coordinate system of RA right ascension also called hour angle, and Declination (Dec)RA is the celestial equivalent of terrestrial longitude. Both RA and longitude measure an east-west angle along the equator; and both measure from a zero point on the equator. For longitude, the zero point is the Prime Meridian; for RA, the zero point is known as the First Point of Aries, which is the place in the sky where the Sun crosses the celestial equator at the March equinox. RA is always zero on the meridian of the celestial sphere which passes through the celestial poles and first point of Aries. Declination is comparable to latitude, projected onto the celestial sphere, and is measured in degrees north and south of thecelestial equator. Therefore, points north of the celestial equator have positive declinations, while those to the south have negative declinations. * An object on the celestial equator has a dec of 0°. * An object at the celestial north pole has a dec of +90°. * An object at the celestial south pole has a dec of −90°.
How does the position of the sun in the sky relate to the length of the shadow cast by an object?
The position of the sun relates to the length of the shadow cast by an object because, when the sun is above the object there is no shadow yet, when the sun is say to the east of the object a shadow is cast towards the west, the farther the sun for example east the longer the shadow will be towards the west.
What are the altitude and azimuth of a star halfway between the horizon and zenith to the due east?
An object seen halfway between the horizon and the zenith has an altitude of 45 degrees.An object seen due east of the observer has an azimuth of 90 degrees.
How far east an object is from the vernal equinox is called?
right ascension

What is 1000 miles east of Quito Ecuador?
Peru if you measure just about right that is what you may get. :)
What is the right ascension of the earth?
"Right Ascension" is a coordinate in one of the main celestial coordinate systems. It is measured eastward along the "celestial equator". The units of measurement are hours, minutes and seconds. Those units are used because the "celestial sphere" appears to rotate once each day. Each hour is the equivalent of 15 degrees. The zero or starting point for right ascension is the "Vernal Equinox". It may seem odd to refer to the Vernal Equinox as the starting point of a coordinate system. The Vernal Equinox is actually a point in space. This point in space is occupied by the Sun at the time we call the Vernal Equinox. You can think of Right Ascension as being the equivalent of the Earth's meridians projected out into space.
From where is the right ascension of the body measured?
Right Ascension is the 'longitude' of celestial objects. The celestial 'Prime Meridian' ... the position defined as zero RA is the celestial meridian that passes through the Vernal Equinox, and the Right Ascension of every point in the sky is measured westward from there. It's expressed in terms of hours, minutes, and decimal seconds, where 1 hour corresponds to 15 degrees of angle. Notice that unlike terrestrial longitude, Right Ascension isn't measured in both directions from the zero meridian. There's no east or west Right Ascension, only one number, that ranges from zero through 24 hours.
Lines of latitude go east west but measure what?
They measure the location of a point north/south of the equator.So ? Have you ever seen a police line-up on TV ? The lines on the background go left and right,but they measure the suspect's height, right ?
