Asteroid Impacting Venus: Will it Strike or Explode?

[willstaruss22]

Lets say you have a 20 km wide stony/iron asteroid hurtling towards Venus at 18 km per second at a 45 degree angle.

Would an asteroid of this size hit the surface of Venus or just blow up in the atmosphere?

I know that an asteroid of this size would hit the surface of Earth but I am curious about Venus and its 93 bar atmosphere.

I started developing a response with this paper: http://www.igpp.ucla.edu/public/mkivelso/refs/PUBLICATIONS/Chyba Tunguska.pdf but I've run out of time lol

The "Fragmentation and Dispersal" section of this article: http://www.gps.caltech.edu/~sue/TJA_LindhurstLabWebsite/ListPublications/Papers_pdf/Seismo_1621.pdf may be of some help as well :) Also check out http://www.researchgate.net/publication/10656063_Efficient_disruption_of_small_asteroids_by_Earth's_atmosphere/file/50463515e55dd85472.pdf
