A) pluto
B) mars
C) mercury
D) venus
Correct Answer: D
Solution :
Venus is the second planet from the sun and the sixth largest. It is the brighest object in the sky except the sun and moon. Venus is sometimes regarded as earth's sister planet. In some ways they are very similar. Venus is only slightly smaller than earth (95% of earth's diameter, 80% of earth's mass). Both have few craters indicating relatively young surfaces. Their densities and chemical compositions are similar. Because of these similarities, it was thought that below its dense clouds venus might be very earth like and might even have life.
