What If Halley's Comet Crashed Into the Moon?

There's a giant, peanut-shaped object orbiting the Sun, and it’s name is Halley’s comet. Like all comets, it’s a cosmic mashup of frozen ice, gases, and dust. Stretching a vast 15 kilometres by 8 kilometres (9 miles by 5 miles), this space snowball streaks by Earth every 76 years and has been circling for 16,000 years. It hasn’t caused us any trouble yet, but that would change if its elliptical return crosses paths with our Moon, causing a devastating collision visible in broad daylight. Would it affect space exploration? How much damage would it do to the Moon? What would happen on Earth?
