SUMMARY
An asteroid measuring 20 km in diameter, traveling at 18 km/s and approaching Venus at a 45-degree angle, is likely to explode in the atmosphere rather than impact the surface. The dense atmosphere of Venus, which exerts a pressure of 93 bars, significantly increases the chances of fragmentation before reaching the ground. Relevant studies, including the "Fragmentation and Dispersal" section from a Caltech publication, provide insights into the behavior of such asteroids in thick atmospheres. The discussion references multiple research papers to support these conclusions.
