What planet has 46 moons?
Jupiter has a total of 67 moons, including the famous “Galilean moons” Io, Europa, Ganymede, and Callisto; Saturn has 62, of which Titan is the most massive and the most famous; Uranus has 27, all named after Shakespeare and Alexander Pope characters; and Neptune has 14, of which Triton is the most massive.7 gün önce
Are you lighter on Mars?
Since Mars has less mass than Earth, the surface gravity on Mars is less than the surface gravity on Earth. The surface gravity on Mars is only about 38% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mars.
What’s heavier steel or lead?
How much does lead weigh, when compared with steel? The specific gravity of lead is 11.34, the specific gravity of steel is 7.8 Or in other words steel is 7.8 times as heavy as water and lead is 11.34 times as heavy as water. One cubic inch of steel weighs 4.566 ounces and one cubic inch of lead weighs 6.644 ounces.
Can you survive inside a black hole?
Time freezes at the event horizon and gravity becomes infinite at the singularity. The good news about massive black holes is that you could survive falling into one. Nothing can escape from inside the event horizon, so you could not escape or report on your experience.

How many kg is the moon?
The moon’s mass is 7.35 x 1022 kg, about 1.2 percent of Earth’s mass. Put another way, Earth weighs 81 times more than the moon. The moon’s density is 3.34 grams per cubic centimeter (3.34 g/cm3).
Is Black Hole dangerous for Earth?
Although their gravity is stronger, the stretching force is weaker than it would be with a small black hole and it would not kill you. The bad news is that the event horizon marks the edge of the abyss. Nothing can escape from inside the event horizon, so you could not escape or report on your experience.
Why does Uranus spin backwards?
Uranus was likely hit by a very large planetoid early in its history, causing it to rotate “on its side,” 90 degrees away from its orbital motion. Venus rotates backwards compared to the other planets, also likely due to an early asteroid hit which disturbed its original rotation.
How much would 10 kg weight on the moon?
Answer: Weight of a 10-kg object on moon is 16.33 N. Answer: Weight of a 10-kg object on moon is 16.33 N. Explanation: If a mass m is under a…
What is on the other side of a black hole?
The event horizon is a proposed boundary around a black hole. On the other side of it, the gravitational pull of the black hole is so strong that, in order to escape it, an object would have to be moving faster than the speed of light, a feat that almost all physicists agree is impossible.
Which planet rotates the fastest?
Jupiter
What two planets have no moons?
The answer is no moons at all. That’s right, Venus (and the planet Mercury) are the only two planets that don’t have a single natural moon orbiting them. Figuring out why is one question keeping astronomers busy as they study the Solar System.
Can a black hole kill Superman?
But if superman enters black hole , using method-1 , then there are very low chances that superman might survive , and pass easily through the black hole. Yet , the chances are very-very-very less , even equal to 1/infinity(not equal to zero).
What’s the smallest heaviest thing in the world?
What’s the heaviest smallest object on earth? The Neutron is the tiniest and heaviest thing known to man kind. It is a subatomic particle.
What is my weight on Mars?
It varies based on factors like your mass, the planet’s gravity, and the distance between you and the planet’s center. If you weighed 100 lbs on Earth, you would weigh only 38 lbs on Mars!
Does Earth have 3 moons?
After more than half a century of speculation, it has now been confirmed that Earth has two dust ‘moons’ orbiting it which are nine times wider than our planet. Earth doesn’t have just one moon, it has three.
Is gold heavier than Mercury?
An atom of gold is lighter than an atom of lead; however, gold is more dense than mercury, so a cubic centimeter of gold is heavier than a cubic centimeter of mercury.
What could be inside a black hole?
What is at the center of a black hole? At the center of a black hole, it is often postulated there is something called a gravitational singularity, or singularity. This is where gravity and density are infinite and space-time extends into infinity.
Can you breathe on the moon?
On the moon, there’s no air to breathe, no breezes to make the flags planted there by the Apollo astronauts flutter. However, there is a very, very thin layer of gases on the lunar surface that can almost be called an atmosphere. In the moon’s atmosphere, there are only 100 molecules per cubic centimeter.
How long is a day on Mars?

Do we have 2 moons?
Astronomers from the Catalina Sky Survey yesterday announced they’d found a second natural satellite orbiting the Earth. It looks like our planet and its long-standing partner Luna have decided to explore polyamory.
