What planet has no impact on tides ?

Eye planets -- Mercury, Venus, Mars, Jupiter and Saturn -- will cluster together on the far side of the Sun. Although the planets will not be in a perfectly straight line, their approximate alignment in a 25 degree-wide region of the sky has triggered speculation in some quarters that interplanetary tidal forces might be magnified, leading to extraordinary effects here on Earth. After all, "Spring Tides" (peak ocean tides that arise bi-monthly) occur when the Sun, the Moon and the Earth are nearly in a straight line around the times of the New Moon and Full Moon. Shouldn't even more powerful tides arise when lots of planets are lined up?

Fortunately, no.

Ocean and crustal tides on Earth will be indistinguishable from normal on May 5th. As a matter of fact, tidal forces from Jupiter and the other planets will actually be at a low ebb this week.

Right: On May 5, 2000, the Moon, Mercury, Venus, Mars, Jupiter and Saturn will converge in an area of the sky about 25 degrees across. Unfortunately, this spectacle will not be visible to sky watchers because of the blinding light of the Sun, which will appear to be right in the middle of this planetary get-together.

"Tides on Earth are dominated by the Sun and the Moon," explains professor George Lebo from the University of Florida Department of Astronomy. "The alignment of the five naked-eye planets just doesn't make a difference. The tidal forces we feel from all those planets put together are thousands of times less than lunar and solar tides. In fact, these forces will be even lower than usual this week because all of the planets are about as far away from us as they can get -- on the other side of the Sun."
