i hav an 8th grade project due and this is the last thing i need to know!What is the longetude and lattitude of the constellation leo?Leo is at right ascension (longitude) 11 hours, declination (latitude) +15掳 North.What is the longetude and lattitude of the constellation leo?A star's position is measured in Right Ascension (Ra) and Declination (Dec), which is stated in very small incriments such as arc seconds. Constellations cover too much area and have broader designations.
Leo is located at 11 hours Ra and 15 degrees Dec., while the brightest star in it, Regulus is located at 10hours, 08 minutes, 22.3 seconds Ra, and 11 degrees, 58 arcminutes, 02 arcseconds. An arcsecond is 1/3600th of a degree.What is the longetude and lattitude of the constellation leo?Some nautical almanacs have tabulated the "latitude" and "longitude" of celestial bodies. It's an old tradition. Ptolemy's coordinates for stars were in terms of latitude and longitude.What is the longetude and lattitude of the constellation leo?
Actually, constellations (like Leo) do not have latitude and longitude, they have right ascension and declination. These coordinates are very much like lat and lon, but applied to things in the sky. You would be very wrong to call them lat and lon, because they're called RA and Dec.
But anyway, the RA and Dec of Leo is roughly RA=11 hours and Dec=15 deg. You probably noticed that RA is measured in hours and Dec is measured in degrees. Yes, that is correct, it has to do with the old mariners and astronomers using the stars for navigation. Since RA is akin to longitude, the unit of hour is the same as a "time zone" on the Earth (24 time zones and 24 hours of Right Ascension).
Good Luck
