Sun is much less than that of the Moon, hut it is measurable. When the solar bulges coincide with the lunar bulges (at "new" Moon and at full Moon), the tides are higher than normal. When a lunar bulge hits a solar "low," the tides are less than normal.

Why is it that no meteorites hit the Earth now, or hardly ever in the present time? John Guild 2809 Burdick Rd. Oak Bay, Victoria, B.C. The Earth is being hit steadily by a hail of meteorites, but the vast majority of them are about the size of grains of very fine sand and burn away before they reach the surface. Really big meteorites, weighing a ton or more, are great rarities and seem to have been rare in the past, too. In the present century, there have been just two known large meteorites. Both of them struck in Siberia, the last one in 1947. But three-quarters of the Earth's surface is water and there are huge uninhabited land areas from which we wouldn't get any reports. The odds, as you can see, are against meteorite strikes in civilized territory, in case anybody happens to be worrying about it.
