The four largest moons of Jupiter are roughly the same size as our Moon and are about 628 million (6.28 ô° 108) kilome- ters from Earth at opposition. What is the size in kilometers of the smallest surface features that the Hubble Space Tele- scope (resolution of 0.1 arcsec) can detect? How does this compare with the smallest features that can be seen on the Moon with the unaided human eye (resolution of 1 arcmin)?
