After an impact with an asteroid or comet, a lot of dust is flung into the atmosphere. All this dust blocks the Sun's light, causing global temperatures to drop, and consequently - longer winters.

The asteroid impact caused mass extinction of the dinosaurs and approximately 75% of all species on Earth. It resulted in wildfires, tsunamis, and a dramatic shift in the Earth's climate due to dust and debris blocking sunlight, leading to a long period of darkness and cold known as the "impact winter."
Ceres is bigger than Halley's comet. Ceres is a dwarf planet located in the asteroid belt between Mars and Jupiter with a diameter of about 590 miles, while Halley's comet has a nucleus estimated to be about 6 miles wide.
Ceres is smaller than any planet; even smaller than Pluto.
That varies completely from comet to comet.
Long period comet
Depends on the asteroid and the comet. The core of a comet is typically anywhere from one mile to up to rarely 50 miles in diameter. As a comets come into the inner solar system they warm, being closer to the sun, and being mostly ice they trail a cloud of gas. On a large comet this gas tail can be vast, millions of miles long. Asteroids come in a huge range of sizes. The largest known in the solar system is Ceres, large enough to be classified as a Dwarf Planet, and has a diameter of about 590 miles. Most are much smaller, all the way down to the size of pebbles or dust.
a long term comet is over 1 year a short term comet is from 0-3 months
The "Comet" is a variety of Goldfish that has a long, single tail.
A comet with a period of 200 years or more.

Scientist aren't sure yet but they have a theory that a huge comet or asteroid collided with the blue planet causing it to spin on its side.
