Halley's comet travels inside of Earth's orbit. It's perihelion is ~0.6au (aphelion is over 35 au). 1 au (astronomical unit) is the distance of the Earth from the Sun.

Halley's comet is roughly equal parts ice and dust. The ice is about 80% water, and most of the rest is carbon monoxide. Yes the Sun's irradiance will sublimate the ice, but there is also a time factor.

Yeah, but the water here starts out as liquid, as stated in the question, I don’t think it would be frozen.

It would nearly immediately freeze.

The vacuum of space would cause water to boil off, drawing energy from the mass until it froze

Oh right, thanks for reminding me of that effect. I concede.
