Any constellation is a group of stars that appear to form some kind of pattern,
but have no connection with each other. They all happen to be in roughly the
same direction from us, but they're all at different distances. So there's no
such thing as a constellation's distance from us.
LHS 3003 is the closest star to earth from constellation hydra.( 20.67 light years away )

18 is the stars of the constellation hydra
The constellation Hydra does not have a specific latitude and longitude because constellations are celestial objects and do not have physical locations on Earth. They are patterns of stars as seen from Earth. The position of a constellation in the sky is measured in right ascension and declination, not latitude and longitude.

Hydra is a constellation made up of many stars. Each star is a different distance from us, so it's impossible to answer how far away it is.
.09c Another Viewpoint: There are a lot of galaxies in the constellation of Hydra. The distance to the main cluster of galaxies (called Hydra 1) is about 165 million light years. This cluster of galaxies has a redshift. Remember the redshift only shows the motion directly away from Earth. The best estimate I have found of how fast it's moving away from Earth is a speed of 0.0114 times the speed of light. That can be written as 0.0114 c. That's quite a bit different from the answer given above.
