That depends on the date, since the sun itself moves through the entire range
of RA during the year.
It also depends on the star's declination. Viewed from the northern hemisphere,
for example, the greater a star's declination, the earlier it rises, and if its declination
is greater than the complement of the observer's latitude, then it never sets.

What are the right ascension and declination of the star procyon?
The right ascension of the star Procyon is approximately 7 hours and 39 minutes, while its declination is approximately +5 degrees and 14 minutes. These coordinates are for the epoch J2000.
What are the right ascension and declination of the star Sirius in the constellation Canis Major?
The right ascension of Sirius is approximately 6 hours and 45 minutes, and its declination is approximately -16 degrees. It is the brightest star in the constellation Canis Major and one of the brightest stars in the night sky.
What does Right Ascension mean?
Right Ascension is a celestial coordinate that measures the eastward angular distance of a celestial object from the vernal equinox, along the celestial equator. It is similar to longitude on Earth but is used in astronomy to pinpoint the position of stars and other celestial objects in the sky. Right Ascension is typically measured in hours, minutes, and seconds.
What star has a right ascension of 14h 05m and a declination of 65 degrees?
This is best answered by finding a star atlas like Norton's or the Sky Atlas 2000.0.
How is right ascension measured in astronomy?
Right ascension in astronomy is measured in hours, minutes, and seconds along the celestial equator, starting from the vernal equinox point. This measurement system is used to locate objects in the sky and is similar to longitude on Earth.
Will a star with a right ascension of 1.0 hours rise before or after the vernal equinox?
Vernal equinox is defined as having right ascension 0; a right ascension 1.0 means it will pass a certain point (horizon, meridian, whatever) 1.0 hours after the vernal equinox.
What are the right ascension and declination of the star Spica in the constellation Virgo?
The right ascension of the star Spica in the Virgo constellation is 1900 13 hours and 25 minutes and the declination is 1900 -10.38'.Spica is the largest and brightest star in Virgo.
What are the right ascension and declination of the star procyon?
The right ascension of the star Procyon is approximately 7 hours and 39 minutes, while its declination is approximately +5 degrees and 14 minutes. These coordinates are for the epoch J2000.
When will a star with a right ascension of 1.0 hours rise?
That completely depends on the date, since the sun itself moves through all values of RA in the course of a year, and our clocks refer to the sun.
Is mercury in the right ascension?
"Right ascension" is just one number for the coordinates of a planet, star, etc. Any such object has a right ascension.
What are the right ascension and declination of the star Sirius in the constellation Canis Major?
The right ascension of Sirius is approximately 6 hours and 45 minutes, and its declination is approximately -16 degrees. It is the brightest star in the constellation Canis Major and one of the brightest stars in the night sky.
Does earth's revolution around the sun change both the right ascension and the declination of a star?
No, Earth's revolution around the Sun does not affect the right ascension and declination of a star. These coordinates are fixed relative to the celestial sphere and are not impacted by Earth's movement around the Sun. Right ascension and declination are used to locate objects in the sky and remain constant over time for a given star.
In star language what does RA stand for?
Right Ascension. It's the celestial equivalent of longitude.
What does Right Ascension mean?
Right Ascension is a celestial coordinate that measures the eastward angular distance of a celestial object from the vernal equinox, along the celestial equator. It is similar to longitude on Earth but is used in astronomy to pinpoint the position of stars and other celestial objects in the sky. Right Ascension is typically measured in hours, minutes, and seconds.
What are the right ascension and declination of the star alderbaran in the constellation Taurus?
According to Wikipedia: Right ascension 04h 35m 55.239s, declination +16° 30′ 33.49″. The data corresponds to the epoch 2000.0.
Can a right ascension and declination for any given star always be the same?
No, the right ascension and declination of a star will change over time due to the Earth's rotation and the star's own motion through space. These coordinates are specific to a particular moment in time and will vary as the Earth orbits the Sun and as the star moves within our galaxy.
What star has a right ascension of 14h 05m and a declination of 65 degrees?
This is best answered by finding a star atlas like Norton's or the Sky Atlas 2000.0.
