Most of us learned the basics about the solar system when we were little. For example, a mnemonic device to help us remember the planets or about the sun being a star, but there are a lot of surprising facts about space that aren't as common knowledge. Here are ten interesting facts that are worth remembering.
1. The reduced gravity in space makes you taller. With the decrease in pressure on the spine you gain about 2 inches in height.
2. If you counted all the stars in the universe and all the grains of sand in the world, there would be more stars.
3. There's no crying in space! Tears can't flow from the lack of gravity. When you really think about it, that's kind of sad in its own right.
4. There is no air to carry sound in space, so literally "no one can hear you scream".
5. Mercury, Venus, Mars, Saturn, and Jupiter are visible to the naked eye for most of the year.
6. "Morning Star" and "Evening Star" refer to Venus. Next to the Moon Venus and Sirius are the brightest objects in the night sky.
7. Venus orbits the sun fully in 225 Earth days, but one rotation on its axis takes 244 Earth days. A day on Jupiter lasts about ten hours making it the windiest, most storm filled planet.
8. The Moon drifts 5 cm farther from Earth each year. If the average life span is 75 years or so the moon that's 3.75 meters in a lifetime, or just over 12 feet!
9. If Saturn could be placed in water it would float because of its low density.
10. Uranus's tilt makes its seasons last about 20 years. That's either really awesome or really horrible. No in between.
The next time you are star gazing try to figure out if you're actually gazing at a planet. Think about how your day would be if it were as long or short as some of the planets in our solar system. When you are sunbathing think how challenging that would be with Venus's atmosphere, Jupiter's wind, or Neptune's distance. Consider all the possibilities of our solar system and universe that remain unknown.
