    ...able to see the moons of jupiter? galileos telescopes were not of high quality by modern standards. he was able to see the moons of jupiter, but he never reported seeing features on mars. use a small angle formula to find the angular diameter of mars when it is closest to the earth. how does it compare to the maximum diameter of jupiter?

    Mars is usually tiny - around 5-6 arcseconds across - and even at opposition, rarely gets much beyond 15 arcsec.
    Jupiter on the other hand, varies between something like 42 arcsec, and 48/49 arcsec (depending where it is in it's orbit)
    Currently not long past opposition, Jupiter is around 46/47 arcsec across.
    Jupiter's moons, appear star-like, but are spread across quite a significant frction of a degree, which makes them easily visible in even 10x50 binoculars
