The square of 1640 is about 2.7 million, and 27,000/2.7 million=0.01). Venus is next, with only 0.6 % of the Moon's force. After that, the numbers drop a lot. The total pull of all the planets combined is 0.017, not even 2% of the Moon's pull!

If you use these numbers like we did above, you see that the Moon's own gravitational effect on the Earth fluctuates by about 25% every orbit! The Moon orbits the Earth in about a month, incidentally, so it goes from apogee to perigee every two weeks. So every 14 days we see a change in gravitational effects from the Moon more than 10 times greater than all the other planets combined!

It's worth mentioning that the "alignment" in 2000 has all the planets on the far side of the Sun. This means that you can add 300 million kilometers to the above distances, and I think you can see that the numbers will drop even more. For example, Jupiter's gravity drops from 0.02 to 0.005, and Venus' tides drop by a factor of 500!
