Comets have been compared to "dirty snowballs"; rocks and dust held together by various types of ice. In deep space, everything cools down because the Sun is so far away, and several elements that we think of as "gasses" are frozen solid in comets.
As the comet approaches the Sun, the Sun's heat begins to melt some of the surface layers into gas, and the sunlight hitting the gas is reflected back to Earth as the "tail" of the comet. Some comets have been known to explode, as the heat of the sun melts a large ice pocket into vapor and breaks off pieces of the comet's core.

Halley's Comet returns to the inner solar system every?
74 yo 76 years
What happens when sunlight hits a comet?
When it is from very far away, nothing. But when a comet approaches the inner Solar System,solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus, carrying dust away with them. That is what we call the 'tail' of a comet.
What does Jupiter clean up or attract?
Large planetesimals from the outer solar system when they are on a trajectory that leads them to the inner solar system. This keeps large enough asteroids and comets from coming into the inner solar system. This was made very aparent during the comet that crashed into Jupiter in the 90's.
What happens when a comet hits a planet?
If the atmosphere does not burn it up then it will hit with the force left over. Most of the time it will leave a crater in the surface of the ground or it will displace a large amount of water if it lands in a body of water. Depending on the size of the comet and the life around it will determine the full extent of the damage.
Is halleys comet part of the solar system?
Yes. Halley's Comet is a comet that orbits our sun, and the definition of "Part of the solar system" is 'Any object that orbits our sun.'
What is the name of an object which enters the inner solar system?
Comet
Is halley comet an periodic comet?
Yes. Halley's Comet returns to the inner solar system about every 76 years.
Halley's Comet returns to the inner solar system every?
74 yo 76 years
Is a comet in the solar system or the galaxy?
A comet is in a solar system. A solar system is in a galaxy, so technically a comet is also in a galaxy.
What does Halley's comet travel through our solar system regularly?
Halley's Comet is PART OF our solar system. Halley's Comet is the best-known of the short-period comets, returning to the inner solar system every 76 years or so. It never gets much further away than the orbit of Neptune.

How often does Halley's comet visit the inner part of the solar system?
Usually once every 76 years.
Will Comet Mitchell aka C1847 T1 ever return if so when?
Comet C1847 T1, "Maria Mitchell's Comet", was on a hyperbolic trajectory and is not expected to return to the inner solar system.

What does Halley's comet mean for the future?
What does Halley's Comet mean for the future? Nothing special; the comet will return to the inner solar system in 2061, and ought to be a pretty special view. But in the grand scheme of things, it has no special significance.

Yes. Halley's Comet is a comet that orbits our sun, and the definition of "Part of the solar system" is 'Any object that orbits our sun.'
