Earth is the fifth-largest planet in the solar system. It’s smaller than the four gas giants — Jupiter, Saturn, Uranus and Neptune — but larger than the three other rocky planets, Mercury, Mars and Venus.
The short answer is this: A day is the length of time between two noons or sunsets. That’s 24 hours on Earth, 708.7 hours (29.53 Earth days) on the Moon.
The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.
Space is a vacuum — so it generally doesn’t carry sound waves like air does here on Earth (though some sounds do exist in outer space, we just can’t hear them).
about -455 degrees Fahrenheit
Far outside our solar system and out past the distant reachers of our galaxy—in the vast nothingness of space—the distance between gas and dust particles grows, limiting their ability to transfer heat. Temperatures in these vacuous regions can plummet to about -455 degrees Fahrenheit (2.7 kelvin).Sep 25, 2020
The pay grades for civilian astronauts are GS-11 through GS-14, based on academic achievements and experience. Currently, a GS-11 astronaut starts at $64,724 per year; a GS-14 astronaut can earn up to $141,715 in annual salary [source: NASA].
Narrator: Scientists have studied a lot of pregnant animals in space, including salamanders, fish, and rats, but not humans. Over 60 women have traveled to space, yet none were pregnant during the trip, let alone gave birth while floating in zero gravity.
She previously worked on a Hubble Space Telescope instrument team. The definition of a day is the amount of time it takes an astronomical object to complete one full spin on its axis.
The Earth is the only planet with an approximately 24-hour day.
