How many stars are there in the constellation Hydra?

I need to know this answer ASAP.... I can't find the answer anywhere! Tell me as much about Hydra and i'll pick you!How many stars are there in the constellation Hydra?You can't find an answer to this question because there _is_ no answer to this question, nor to any other question about how many stars there are in any constellation. That's because the number of stars depends on how faint you want to go with the stars. If you want to know how many first magnitude stars there are in Hydra, the answer is zero. If you want to know how many 20th magnitude stars, the answer is millions. You can't even ask how many stars make up the usual constellation pattern in Hydra, because that varies from book to book.How many stars are there in the constellation Hydra?The sprawling constellation of Hydra was one of the 48 constellations listed by Ptolemy and endures today to be the largest of the 88 modern constellations adopted by the International Astronomical Union. Spanning an incredible 1303 square degrees of night sky and containing 17 primary stars in the asterism, Hydra contain 75 stars with Bayer/Flamsteed designations. It is bordered by the constellations of Antlia, Cancer, Canis Minor, Centaurus, Corvus, Crater, Leo, Libra, Lupus, Monoceros, Puppis, Pyxis, Sextans and Virgo. Position south of the ecliptic plane, Hydra is visible to all observers at latitudes between +54掳 and ?83掳 and is best seen at culmination during the month of April.



Shall we begin with a binocular tour of Hydra? Then let's start first with the small asterism of stars which marks the "head" of Hydra located between bright stars Regulus and Procyon. When you've picked out this distorted circlet, focus your attention on the northernmost of these stars - Epsilon - the backward "3" on our map. While to binoculars it might seem rather ordinary, Epsilon is actually a fantastic multiple star system with at least five members! The primary is a yellow-white giant star with a white subgiant star orbiting so close that it is considered a spectroscopic binary star. A bit further away is another binary pair, the G and F star鈥?and further away yet is a class M dwarf star. Be sure to take out your telescope and have a look鈥?



Now move southeast for the brightest star in Hydra - Alpha - the "a" symbol on our map. Its name is Alphard and it is located about 175 light years away from Earth. Shining in a very soft orange color, this giant star reaches temperatures of about 4000 degrees Kelvin and if at home in our solar system would be about 400 times brighter than our Sun. What makes Alphard unique? Its barium content. At one time Alphard, too, was a binary star, but its massive companion is long gone. Alphard happily collected its by-products of nuclear fusion and left us with evidence of what once was!How many stars are there in the constellation Hydra?According to Bright Star Catalog, there are 127 stars down to 6th magnitude. This means that on a very dark night sky, using the limit unto which magnitude the naked eyes can see, we will see as many as 127 stars making up the giant Hydra constellation patterns.How many stars are there in the constellation Hydra?
your question cannot be answered, bcuz it doesn't state the magnitude of the stars to be counted. that's why you can't find any answers.



who keeps giving this stupid assignment?
