180.50 light years away.
"Libra" is a constellation ... a group of stars that seem to join in a pattern when viewed by humans on Earth, in a region of the sky defined by human astronomers on Earth. The stars in Libra are totally unrelated to each other, and each of them is at a different distance from Earth.
One Astronomical Unit is the mean distance between the Sun and the Earth.
The average distance between Sun and Earth is called the "astronomical unit". It is approximately 150 million km.
Paris. The moon is about 220,000 miles away from Earth. Earth's circumference is about 25,000 miles. Paris is much closer to New York (3,636 miles) then the moon (238,857 miles). No distance between two places on Earth is greater than the distance to the moon. The circumference of the Earth is only 24,901 miles so that's pretty much the furthest you can go between two points on Earth. The distance to the moon as mentioned is over 238,857 miles.
The light from Betelgeuse, a red supergiant star in the constellation Orion, takes approximately 642.5 years to reach Earth. This distance means that when we observe Betelgeuse today, we are actually seeing it as it was over six centuries ago. The exact distance can vary slightly due to the star's position and motion, but 642 light-years is the commonly accepted estimate.
Bootes is composed of many stars, each with a different distance from the Earth, so the question cannot be answered.
Bootes is a constellation, not a single star. It comprises 164 stellar objects and their distances from earth range from 22 light years to 6,037 light years: take your pick!
The stars in the constellation Boötes are at varying distances from Earth, with the closest star being around 37 light-years away and the farthest stars in the constellation being thousands of light-years distant.
Epsilon Boötis (ε Boo / ε Boötis) is a star in the constellation Boötes. It has the traditional names Izar and Pulcherrima. It is actually a binary star, consisting of a bright orange giant and a smaller main sequence star. Epsilon Bootis is approximately 300 light years from the Sun/Earth.
Beta is not a constellation.
All constellations are imaginary diagrams formed by patterns of many stars - each one it's own unique distance from Earth. So a constellation isn't a particular distance from Earth - as the stars only look like they're next to each other from our perspective here on Earth.
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.
The constellation Grus is approximately 17.08 light-years away from Earth.
If you mean the constellation cancer, there is no such thing as a "distance to a constellation". It just doesn't make sense. A constellation is basically a general direction in space.

Like all constellations, they are made up of stars - each one it's own unique distance from Earth. Therefor a constellation isn't a specific distance from Earth.
Ursa Major or Great Bear is a star constellation. As such, one cannot think in terms of the distance to it because the stars that make up the constellation are not located in the same general area in space. Epsilon UMa, one of the stars that make up the constellation is also the closest at 64 light years.
