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.
No it isn't

No. For one thing, Halley's comet is a comet, not an asteroid. The largest asteroid is Ceres, which is far larger than Halley's comet.
They all are bigger than an asteroid.
a comet explosion is more stronger and bigger than a nuke explosion and atomic bomb but not a hydrogen if you want something to be mor bigger than a hydrogen explosion call in a asteroid that's bigger than a hydrogen explosion and some meteors. ps I am the maker of the awnsers web site
It IS an asteroid. (The biggest.)
asteroid
A comet consists of meteors and naturally it ought to be bigger than a meteor.
Comet
No, Halley's comet is smaller than the Moon
An asteroid
An asteroid-sized chunk of rock with a tail would be a comet.
no
No. Pluto is considered a "dwarf planet" and in terms of composition is more like a comet than an asteroid.
