Yes. In fact, the Earth is falling closer to the Sun every day, until it reaches perihelion on January 4. The Earth's orbit is elliptical; in fact, ALL orbits are elliptical. The difference between aphelion (furthest distance from the Sun) and perihelion (the closest distance to the Sun) for the Earth is nearly three million miles.
Just ONE - the North pole !
1.6 is a useful approximation. 1.609 is closer. 1.609344 is even closer. There's no exact number.
The one that is closer will move at a higher speed. The same happens, for example, with planets revolving around the Sun - the planets closer to the Sun move faster.
One reason could be that the brighter star is larger and hotter, emitting more light. Another reason could be that the brighter star is located closer to Earth, making it appear brighter in the sky.
There are 5280 feet in a mile. So 1000 feet is between one-tenth and two-tenths of a mile. It is much closer to two-tenths of mile than one-tenth. Two-tenths of a mile is 1056 feet so is within just 56 feet of 1000 feet.
yep, it will be a bit hot if there was one any closer
Which body? The one casting the umbra or the one on which it fell? Try it this way: If the Earth and the Sun stayed the same distance apart but the Moon was closer to the Earth, the umbra it made during eclipses would be larger; if it were closer to the Sun (i.e., farther from the Earth) the umbra would shrink, perhaps to nothingness, and only the penumbra would fall on the Earth.
Scientists estimate that we have 326 million cubic miles of water. That means if I had a cube one mile by one mile by one mile and filled it with water that would be one cubic mile. So,if I had 326 million of those cubes (all filled with water) then that would be about the same amount of water on the Earth. About 72% of Earth is covered in water but 97% of that water is useless because it is salty.3% of water is left but 70% of 3% is frozen so we only have less than 1% of the Earth's water.
You drove a mile in reverse.
There is evidence that the continents were once close, because if you look at a map for the earth, It looks like the earth is a big puzzle. Saudi Arabia fits into Eurasia, South America can interlock with Africa, and if you moved all the little islands between US and Europe, the could slide in. As you can see, there is evidence that the continents may have been closer at one time.
Section-A one-square-mile block of land, containing 640 acres, or approximately one thirty-sixth of a township. Due to the curvature of the Earth, sections may occasionally be slightly smaller than one square mile.
A "Knot" is a unit of speed equal to one nautical mile per hour. Traditionally, one nautical mile is equal to one minute of latitude on the Earth's surface. From Wikipedia: the international standard is 1 nautical mile = 1,852 metres exactly.
