Uranus has the surface area of 15.91 Earths. It has the volume of 63.086 Earths. It has the mass of 14.536 Earths. Its diameter is 4.007 times that of Earth. See the related link for more information.
If a car could be placed on the equatorial surface of Jupiter, it would weigh approximately 2.52-2.54 times what it would on earth, so exact weight depends on type of car. As Jupiter is a gas giant planet, it does not have a solid surface so the car would actually sink into the planet, melt in the interior and become a minor contaminant.
No. Even if everybody were to run in the same direction around the earth they would effect the rate of rotation only very very slightly. You have to calculate the total angular momentum produced by the running population and subtract (or add depending on the direction that they run) the total angular momentum on the earth, (first calculate the moment of inertia of a solid iron sphere the size of the earth then multiply by the angular velocity (circumference of the earth over a 24 hour period)). I'm sure you will find that the value for the earth wins out by a considerable margin. It would be an interesting calculation to make however. Population of the earth times the average mass of a person, times the medial running speed times the radius of the earth. I'll let someone else do that.
Lava is magma that is erupted onto Earth's surface. The temperature is essentially the same, except for the cooling that may occur after eruption.
1 kg is not equal to 9.8 newton. It's the amount of mass that weighs 9.8 newtonon earth.The weight of anything is(object's mass) times (the local acceleration of gravity).When the same mass moves to places with different gravity, its weight is different.The acceleration of gravity anywhere on or near the surface of the earth is 9.8 meters per second2 .The weight of 1 kilogram of mass anywhere on or near the surface of the earth is(1 kilogram) times (9.8 meter per sec2) = 9.8 kilogram-meter/sec2 = 9.8 newton.
4300 kilometers
Antarctica covers about 9% of the Earth's land surface, which is about 3% of the total surface, or about 14 million square kilometers. It is about as 1.5 times as big as the US.
The surface of the earth has an area of approx 510.1 million sq km → 510.1 million km² ÷ 4.9 million km² ≈ 104.1 times.
109 Actually, no. 109 would probably be for Jupiter. For Earth, hundreds of Earth's surface could fit in the sun's radius.
The Moon's gravity is 6 times weaker than that on the Earth's surface.
No, it is so hot on the surface that led melts, and the pressure is 990 times the pressure on Earth.
At the surface, it is 2.64 times its value at the Earth's surface.
-- The earth's diameter (distance through the center) is about 3.7 times the moon's diameter. -- The earth's surface area is about 13.5 times the moon's surface area. -- The earth's volume is about 49.5 times the moon's volume. -- The earth's mass is about 82 times the moon's mass.
As you may know, gravitic force is measured from the center of the body or mass. So . . . Nepune is 17 times more mass-ive than Earth (heavier), but any point on its surface is 3.8 times farther from Neptune's center than a similar location on Earth. Gravitic force lessens by 4 times when you move another mass 2 times farther away from it. The result is that, despite being huge in comparison to Earth, Neptune's force of gravity at its surface is only 1.14 times the force of gravity on earth's surface. So, if you weighed 150 pounds on earth, you would weigh 165 pounds on Neptune, if you could manage to stand on its surface. (Its surface is not solid like Earth's)
About 2.5 times that on Earth
Earth has 2.54 times the surface area of Mercury. Earth-12,756 km Mercury-4,880 km
