The new comet, Hale-Bop, was very bright when it came past about 6 years ago.
Yes, there are many comets other than Halley's comet. Comets are icy bodies that orbit the Sun and often have elongated orbits that bring them close to the Sun. Some well-known comets include Hale-Bopp, Comet NEOWISE, and Comet Lovejoy.
Comets get brighter the closer they get to the sun for two reasons: the sunlight is brighter closer to the sun than it is further away and the comet heats up closer to the sun causing outgassing and the formation of a large coma composed of dust particles and gas around the comet itself giving a much larger area for sunlight to reflect off of.
Venus is occasionally brighter than jupiter
Comets are ephemeral, though a few recur with a regular period. Halleys Comet is the classic example of this. Some comets have return periods considered greater than, or comparable with the age of the universe. Many are bound within the Solar System, with one of their orbital foci near the Sun, and the other in their region of origin. A Comet consists of a body containing evaporable material - ice or gas - and depending upon how close to the Sun they pass, they will eventually lose most of their mass. The comet's tail points away from the Sun, and is made from the volatile components evaporated by the Solar Wind or by particles from the Sun.
Because comets cannot decide when they will be visible. It was a natural phenomena and remains so. Comets have a 'year' as do all solar objects. Halleys comets year happened to coincide with the battle. It was a coincidence, nothing more than that.

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
By themselves, comets are not really important. Even the most impressive comet, like Hale-Bopp, is a visual spectacle only. But the POTENTIAL for a comet - to strike the Earth directly and cause untold devastation - is far more significant. Right now, if we were to see a comet aimed at the Earth, there is very little that we could do about it, other than stand there and die. The threat of a comet impact, like the ones that have devastated our planet several times before, ought to be enough spur us all into looking for ways to protect ourselves from the inevitable time that it WILL happen again.
The Moon is bigger. It has a diameter of 2,159 miles (3,476 kilometers), which is about four times smaller than the diameter of Earth. Halley's Comet nucleus (the solid bit) is estimated to be approximately 5 miles by 9 miles.

Yes green is brighter than yellow
A star that is brighter than another.
Aqualung, "Brighter than sunshine". Aqualung, "Brighter than sunshine".
Arcturus is a bit brighter than Vega, actually.
No, Halley's comet is smaller than the Moon
The former is 10 times brighter than the latter.
Brighter Than Sunshine was created on 2003-10-13.
