At the end of December 2011, the following comets are
all brighter than magnitude 12 as seen from Earth:
-- C/2009 P1 Garradd
-- P/2011 Y1 Levy
-- C/2011 W3 Lovejoy
-- 21P Giacobini-Zinner
According to NASA, on November 28, 2013, Comet ISON may briefly become brighter than the full Moon.

I think I has to be Halleys Comet
SOHO
On a year in-year out basis, the top three in order are the Sun, the Moon and Venus. An occasional very bright comet, or an even rarer supernova visible on earth can take over spot #3, though.
Jupiter, the giant spot on Jupiter is actually a massive storm.
The earth rotates but the rest of the universe does not. So in your winter, you are facing Orion. But in fall, the earth(with you on it) has spun past that particular spot in the universe.
Yes. The Moon is always "out" in the sense it's never "in" anything (well, it's "in" the solar system and the galaxy, in the sense that it's a part of them). I think what you're trying to ask is if the moon is "up"... that is, visible in the sky... at all times, in which case the answer is "yes" if you mean "from somewhere on Earth" and "no" if you mean "from a particular spot on Earth." On average, the moon is visible from any given spot on Earth approximately half the time... sometimes at night, and sometimes during the day, though it's obviously more noticeable at night.
3 times the size of earth there is also a little red spot and astronomers believe that the big red spot will eat up the little red spot.

Probably for a long long time, as Inky has yet to be named as a comet, but if you're lucky and spot a new comet, you are at liberty to name it Inky if you like.

No. The Great Red Spot is a storm.

Meteor "showers" happen when the Earth passes through the orbit of a comet, or where a comet once was. Most of the meteors are dust-sized, and when a comet approaches the Sun, the Sun's heat and light melt some of its ice and blow the dust and vapor into the "tail" of the comet.But the dust continues along in the same orbit as the comet; just a little slower.The ancient comet's orbit passes near the Earth at one spot along the Earth's orbit, and the Earth goes through pretty much the same path each year. So meteor "showers" happen on the same day each year.
Haley's comet is a comet that passes around every 76 years, it was last seen in 1986 and will next be seen in 2061. It is the only short-period comet that is visible to the naked eye. It's orbit is highly elliptical and focuses on the sun.Correctly named Halley's comet, this comet was named after Edmond Halley in 1705 and is visible to the naked eye about twice in a person's lifetime.
At least with the naked eye, yes. Comets can become visible around the time they pass the orbit of Mars, though on its own a comet-sized object would not be visible to the naked eye anyway. However, it is possible to spot such objects with advanced telescopes.
