Is it a star that for the 2nd night pretends to be another Galilean moon


Recommended Posts

It's just a star. In its motion through the sky, Jupiter regularly passes close to many stars, which sometimes line up to look like another moon. None of the non-Galilean moons are bright enough to be seen as anything but a very faint object even in large scopes.

Wouldn't agree with this as I can see 3 and sometimes 4 of the moons around Jupiter in 8x42 binoculars.

42mm isn't a very large scope and in a small 70mm scope the moons are all very visible, Io stood out from the other 3 as it was much brighter last time I looked, again 70mm is not a very large scope.
