   👍 to this idea, and also re-writing the wide range of code in astropy.coordinates.test to use this uniformly.

   Would it be sufficient to just check if the angle between the coordinates is below some threshold?

   @sargas - yes, using the angular separation functions already in astropy, so should be easy!

    This is simple to write with existing functions:

    import astropy.units as u
    u.allclose(c1.separation(c2), 0*u.deg)

    so I'm going to close this, but feel free to reopen if you disagree!
