Abstract:
Although Venus bas long been thought of as Earth’s sister planet, it spins very slowly – only one retrograde revolution in 243 days. It has been suggested [1,2] that the rotation could be increased by bombarding the planet with ice-moons or asteroids off-centre. However, rotation periods as short as 24 hours are not easily obtained. Moreover, the procedure is a costly one, using up far too many valuable asteroid and far more water-ice than is actually required for the creation of planetary oceans. Serious loss of atmosphere to space may also result.
