We rarely see a good comet when it's at its best. Most comets are brightest when nearest the Sun â€” just when theyâ€™re most likely to be hidden in the Sunâ€™s glare or below the sunrise or sunset horizon.
That's the situation this spring with Comet C/2009 R1 (McNaught). Even so, observers in the Northern Hemisphere should be able to pick it up with telescopes, and possibly binoculars, just before dawn for at least part of June, during its runup in brightness.
Some reports say this comets atmosphere is bigger than Jupiter so what would happen if it were to hit it.
