After the first moonwalk in 1969, Pan American Airlines began accepting reservations for commercial flights to the moon, dates and time unspecified. More than 90,000 requests poured in immediately.

Afternoon temperatures on Mars go up to about 80 F in some areas, and down to -190 F at night.

All the coal, oil, gas, and wood on Earth would only keep the Sun burning for a few days.

All the planets in our solar system could be placed inside the planet Jupiter.

Although the sun is 400 times larger than the moon, it appears the same size in the sky because it is 400 times farther away.

An area of the Sun's surface the size of a postage stamp shines with the power of 1,500,000 candles.

An estimated 10,000 million of the 100,000 million stars in our galaxy have died and produced white dwarfs.

An object weighing 100 pounds on Earth would weigh just 38 pounds on Mars.

If an object has no molecules, the concept of temperature is meaningless. That's why it's technically incorrect to speak of the "cold of outer space" space has no temperature, and is known as a "temperature sink," meaning it drains heat out of things.

If Earth was the size and weight of a table tennis ball, the Sun would measure 12 feet and weigh 3 tons. On this scale, the Earth would orbit the Sun at a distance of 1,325 feet.

If Earth was the size of an apple, the atmospheric layer would be no thicker than the skin of the apple.

If Earth were the size of a quarter, the Sun would be as large as a 9-foot ball and would be located a football field's distance from Earth.

If one were to capture and bottle a comet's 10,000-mile vapor trail, the amount of vapor actually present in the bottle would take up less than 1 cubic inch of space.

If our whole galaxy were the size of a quarter, our solar system would be smaller than the size of a molecule. Other galaxies would be from a foot to 1,000 feet away.

If the Milky Way Galaxy was the size of the U.S.A., Earth would be far smaller than the smallest particle of dust, barely visible through the most powerful microscopes.

If the Moon were placed on the surface of the continental United States, it would extend from San Francisco to Cleveland (2,600 miles).

If the Sun were as wide as a man was tall, Betelgeuse, the biggest known star, would be as wide a three Eiffel Towers stacked on top of each other.

If the world were to become totally flat and the oceans distributed themselves evenly over the earth's surface, the water would be approximately 2 miles deep at every point.

Ancient Chinese astronomers first observed sunspots about 2,000 years ago. Westerners took quite a while to catch up, first writing of the dark blotches 1,700 years later, and erroneously believing them to be small planets.

Antarctica has been used as a testing laboratory for the joint United States-Soviet Union mission to Mars because it has much in common with the red planet.
