Planets that have strong magnetic fields also have rapid rotation and convective fluid interior zones that are also good electrical conductors. The magnetic field of Venus is so weak that it has not yet been detected, which makes it at least 25,000 times weaker than Earth's magnetic field. Examine the Venus data file in your textbook. What information here may indicate why Venus is lacking a strong magnetic field?

Answer: Because its period of rotation is 243.01 days (retrograde)

Explanation:

In comparison, Earth rotates once in about 24 hours with respect to the Sun, but once every 23 hours, 56 minutes, and 4 seconds with respect to other, distant, stars. Earth's rotation is slowing slightly with time, so in the past a day was shorter.
