If Haley's comet was to hit Venus, what effects would it have?

Answer 1

Haley comet having the time of the rotation around the sun relative to earth around 76 years per turn, So our duty is to wait for its return . Why worried.

Answer 2

The comet would be vaporized.

Answer 3

It would likely hit with great force, as Halley's accelerates as it falls toward the Sun;  the image we'd see would probably be on the order of what we saw when pieces of the comet Shoemaker-Levy 9 impacted Jupiter - huge explosions, releases of energy... I bet Venus would have a very large crater on it's surface (that we'd only be able to see through radar imaging), and that the temperature of Venus' atmosphere would rise for a slight period, before settling back to what it is now.

Answer 4

It would be good for Venus.   It would cool Venus down some and increase the amount of water there.

Answer 5

The correct name is Comet Halley (note double L).  As a lump of ice with some embedded pebbles, hitting a very dense atmosphere with a temperature of 870 degrees Fahrenheit, the Solar System would have one less comet, and Venus would barely notice.
