Here are some out-of-this-world things about the universe.
Space is completely silent because molecules are too far apart to transmit sound. That’s because there’s no air in space. It’s a near perfect vacuum. The temperature in the void of space is about −270.45 °C. BRRR!
The sun is the center of the solar system and makes up 99.8% of the solar system's mass. It’s also 400 times the size of the Moon. So how can the Moon block the Sun during a solar eclipse? Because the Moon is roughly 400 times closer to Earth, it appears about the same size as the Sun. Objects closer appear larger than objects far away!
30 Earth-sized planets could fit in between Earth and the Moon.
Twice every 29 and a half years, Saturn appears ringless. But it’s an optical illusion. Due to the angle of the rings, they’re not visible from Earth and barely detectible through telescopes.
Scientists believe there are more stars in the universe than there are grains of sand on all of Earth’s beaches. It’s estimated that there are 100-400 billion stars in our Milky Way galaxy and about 1,000,000,000,000,000,000,000 (that's 1 billion trillion) in the universe.
The largest asteroid in the solar system is roughly 329 miles in diameter.
A full NASA space suit reportedly costs at least $15,000,000 with a significant portion of that going to the backpack and control module. A fully equipped space suit is basically a mini, human-sized, spaceship.
The International Space Station is the largest orbiting lab ever built.
The footprints from the Apollo astronauts moon landing in 1969 will probably still be there millions of years from now.
