Even though our planet is a sphere, it is not a perfect sphere. Because of the force caused when Earth rotates, the North and South Poles are slightly flat. Earth’s rotation, wobbly motion and other forces are making the planet change shape very slowly, but it is still round.

Earth has a diameter of roughly 8,000 miles (13,000 kilometers) and is round because gravity pulls matter into a ball. But our home planet isn’t perfectly round, rather, Earth is really an “oblate spheroid,” because its spin causes it to be squashed at its poles and swollen at the equator.

It is an oblate spheroid. It’s flattened at the poles and bulges at the equator. The Earth is 12,756km at the equator and 12,714km from pole to pole. We round this up to 13,000km.

Titan is the second largest moon in our solar system. Titan is bigger than Earth’s moon, and larger than even the planet Mercury.

(WKBN) – Have you ever wanted to know how far the sun is from the earth? Here are some fun facts about the distance to the sun: On average, the sun is 93 million miles from the earth. It would take 1,430,769 hours to drive there at 65 miles per hour.

384,400 km

Chimborazo is in the Chimborazo Province of Ecuador, 150 km (93 mi) south-southwest of the city Quito, Ecuador.

“When the moon is near the horizon, the ground and horizon make the moon appear relatively close. Because the moon is changing its apparent position in depth while the light stimulus remains constant, the brain’s size-distance mechanism changes its perceived size and makes the moon appear very large.

Why do you think getting to space is so difficult when it’s only 62 miles away? Answer: Space is 62 vertical miles away. It takes a lot of energy to overcome gravity for that distance and gain the speed required to stay in orbit (approximately 17,500 miles per hour) once you’ve arrived.

The space station is made of parts that were assembled in space by astronauts. It orbits Earth at an average altitude of approximately 250 miles. It travels at 17,500 mph. This means it orbits Earth every 90 minutes.

Expedition 62 to the International Space Station (ISS) began on Feb. 6, 2020, with the departure of the Soyuz MS-13 spacecraft. The Expedition currently consists of three crewmembers: Cmdr. Oleg Skripochka of the Russian space agency Roscosmos, as well as two NASA astronauts, Jessica Meir and Andrew Morgan.

The current ISS occupants are NASA astronauts Megan McArthur, Mark Vande Hei, Kimbrough, Hopkins, Walker and Glover; JAXA’s Noguchi and Akihiko Hoshide; the European Space Agency’s Thomas Pesquet; and cosmonauts Oleg Novitskiy and Pyotr Dubrov.

As a result NASA’s official policy forbids pregnancy in space. Female astronauts are tested regularly in the 10 days prior to launch. And sex in space is very much frowned upon. So far the have been no confirmed instances of coitus, though lots of speculation.

A Maximum Absorbency Garment (MAG) is an adult-sized diaper with extra absorption material that NASA astronauts wear during liftoff, landing, and extra-vehicular activity (EVA) to absorb urine and feces. Astronauts can urinate into the MAG, and usually wait to defecate when they return to the spacecraft.

Studies have shown that women can have periods as normally in space as they do on Earth. What’s more, menstrual blood flow isn’t actually affected by the weightlessness we experience in space, so it doesn’t float back in – the body knows it needs to get rid of it.

(AP) — How do astronauts do laundry in space? They don’t. NASA wants to change that — if not at the International Space Station, then the moon and Mars — and stop throwing away tons of dirty clothes every year, stuffing them in the trash to burn up in the atmosphere aboard discarded cargo ships.
