It's impossible to give a single distance for the Leo constellation because it's not a single object. It's a group of stars that appear close together in the sky from our perspective on Earth.

The stars in Leo are at varying distances from Earth. Some are relatively close, while others are incredibly far away.

For example:

* Regulus, the brightest star in Leo, is about 77 light-years away.

* Denebola, another prominent star in Leo, is about 36 light-years away.

So, the distance to Leo depends on which star you're considering.
