Here it is: Your astronomy and Earth quiz! (sort of long)

[AHunter3]

I’ll be annoyed if I don’t ace this one. My astronomer geek days were Junior High, though, so I could be out of date / out of touch…

**Mercury

Venus

Your numbers are way off Press according to these sites. But Venus still wins, but by a much smaller margin. Mercury max is 700K. Venus mean is 726K. Dammit, I had debated said Venus might be it but I caved and went for Mercury, nuts. **

Wow, really? Whoa.

Well, thanks for checking it out and getting the right numbers. Greatly appreciated.

[Earl_Snake-Hips_Tucker]

Didn’t the Great Dark Spot disappear a few years ago?

[Yo_La_Tengo]

Nonetheless, I am here. Let’s see what y’all got…
[ul][li]What are the nine planets, in order, starting from the sun? [/li]Correct answer: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune/Pluto. I think all of you got that.

[li]What are the nine planets, in order, from largest to smallest? [/li]Correct answer: Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars, Mercury, Pluto. A few mixed up Neptune and your anus… err Uranus.

[li]What planets are known as gas planets? [/li]Correct answer: Jupiter, Saturn, Uranus, Neptune. Saw the correct answer a few times…

[li]What are the names of all the planets that have (known) rings? [/li]Correct answer: Jupiter, Saturn, Neptune, Uranus. Most people miss Jupiter because there aren’t any visible rings from Earth, but when the Voyagers flew by they saw at least two rings, I think.

[li]What is the densest planet in the solar system? [/li]Correct answer: Earth. According to a book called The Universe, it’s density is about 5.5 times that of water.

[li]What is the least dense planet in the solar system? [/li]Correct answer: Saturn, with a density of about 0.68 times that of water; 1/8 that of Earth.

[li]What planet has the longest day? [/li]Correct answer: Venus. According to The Universe, a day on Venus is equal to 243 Earth days. Mercury’s day is only 59 Earth days.

[li]What planet has the shortest day? [/li]Correct answer: Jupiter, with a day equal to 10 Earth hours.

[li]What planet has the most moons? [/li]Correct answer: Saturn, with 18+ moons. Jupiter has a lousy 16+.

[li]What is the hottest planet? [/li]Correct answer: Venus.

[li]What is the coldest planet? [/li]Correct answer: Pluto.

[li]How many moons does Earth have? [/li]Correct answer: One. I think it’s hilarious when people don’t know that.

[li]How many moons does Mercury have? [/li]Correct answer: None.

[li]How many moons does Venus have? [/li]Correct answer: None.

[li]How many moons does Pluto have? [/li]Correct answer: One.

[li]How many moons does Mars have? [/li]Correct answer: Two.

[li]What is the name of Mars’ moon(s)? [/li]Correct answer: Phobos & Deimos.

[li]What is the name of Pluto’s moon(s)? [/li]Correct answer: Charon.

[li]On what planet is the tallest mountain in the solar system? [/li]Correct answer: Mars.

[li]What is that mountain called? [/li]Correct answer: Olympus Mons.

[li]What is it’s (approximate) height? [/li]Correct answer: ~29 km (18 miles)

[li]How often does Halley’s comet come around Earth? [/li]Correct answer: 76 years.

[li]What is strange about Pluto’s orbit? [/li]Correct answer: Its very elliptical. So much that it swings inside of Neptune’s orbit and becomes the 8th closest for a short amount of time.

[li]What is strange about Pluto’s orbit? (Another) [/li]Correct answer: The eight other planets more or less make the solar system “flat.” Pluto’s orbit kind of breaks that rule.

[li]What planet has The Great Dark Spot? [/li]Correct answer: Neptune. Jupiter has the Great Red Spot. Gotcha.

[li]What planet has a “severe tilt” to it? [/li]Correct answer: Uranus, so much so that it appears to be on its side. Its axial tilt is 97.9 degrees.

[li]What is the Oort Cloud? [/li]Correct answer: The source of most comets in the solar system, and is said to be the true boundary of our solar system.

[li]What is the closest star to the Earth? [/li]Correct answer: The Sun. (93,000,000 miles)

[li]What is the 2nd closest star to the Earth? [/li]Correct answer: Proxima Centauri. (27 trillion miles)

[li]What’s the name of the Red Supergiant that sounds a lot like a “person” you could find at Universal Studios? [/li]Correct answer: Betelgeuse.

[li]What color are the hottest stars? [/li]Correct answer: Blueish-white.

[li]What’s our galaxy called? [/li]Correct answer: Milky Way.

[li]What kind of galaxy is our galaxy? [/li]Correct answer: Spiral.

[li]What are the three main kinds of galaxies? [/li]Correct answer: Spiral, Elliptical, and Barred. You may complain, but that’s what I learned it school. I said “main” so you wouldn’t say irregular.

[li]What is a light-year? (definition) [/li]Correct answer: Distance light travels in one earth-year.

[li]How long is a light-year? (number) [/li]Correct answer: 10 trillion km (6 trillion miles).

[li]What is the most abundant element the universe? [/li]Correct answer: Hydrogen.

[li]Will the sun ever go supernova? [/li]Correct answer: No

[li]What’s odd about the sun’s rotation? [/li]Correct answer: Different sections rotate at different speeds. The poles move faster than the equator (the total opposite what Finch said).

[li]In what year did Sputnik I go up? [/li]Correct answer: 1957.

[li]How long does it take sunlight to reach the Earth? [/li]Correct answer: About 8 minutes, I forgot the seconds part.

[li]About how old is the Earth? [/li]Correct answer: ~4.6 billion years.

[li]What’s the Earth’s (approximate) diameter? [/li]Correct answer: ~8,000 miles.

[li]About what percent of the Earth’s water is in the oceans? [/li]Correct answer: ~97%. I think 2% is in the ice sheets.

[li]What is the most abundant element in the Earth’s atomsphere? [/li]Correct answer: Nitrogen.

[li]What is the tilt of the Earth on its axis? [/li]Correct answer: 23.5.[/ul]

Nice work, everyone. I’m too lazy to see who got the most answers right, but whoever you are, congratulations.

[Yo_La_Tengo]

Oh yeah…

No, we did astronomy a few months ago. Watch out for an earthquake quiz, though. Then it might be.

I believe you’re right about the Great Dark Spot.

Damn, I got 8 wrong. That’s terrible! Attrocious! I should have gotten the Sun/ Proxima ones right. I should have read question 44 more carefully and I would have gotten that right. Sigh. But I guess not bad for a guy 6 years out of Astronomy.

[Race_Bannon]

I didn’t really take your quiz, but I think I would’ve done pretty well.

A more obscure way to ask #46 would be “What is the obliquity of the ecliptic?” - sounds more mysterious.
