6. Jupiter has an apparent magnitude of -1.67, but an absolute magnitude of 25.87. Neptune has a magnitude of 7.84 but an absolute magnitude of 32.08. Which planet can you see with the naked eye? Which can you see with a telescope only? If we imagine that these planets were at a distance of 10 parsecs, would we be able to see either of them with the Hubble telescope? Use Google or another to check the limiting magnitude of the Hubble space telescope.
