Mercury is the smallest planet, and as a consequence has the smallest gravity. Mars is not as dense as Mercury, but is so much larger--it has the second lowest surface gravity.
Eris (which is larger than Pluto), has less gravity than Mercury, but it along with Ceres and several other large solar system objects are considered "dwarf" planets.

What is the escape velocity of the moon Charon?
Charon is the largest satellite of the dwarf planet Pluto and has an escape velocity of 0.36 mi/second or 1,296 miles per hour.
What is the escape velocity of Mars?
The escape velocity on the planet Saturn is 35.5 kilometre per second. That is, a body has to be projected with a velocity of 35.5 kilometre per second so that it can escape from the gravitational pull of the planet. (Escape velocity on the earth is about 11.2 kilometre per second.)
How fast must an object go to leave a planets gravity?
The speed that ab object must travel at to escape a planet's gravity is called escape velocity. This value varies depending on the mass and diameter of the planet. Here are the escape volcities of the eight planets of our solar system. Mercury: 9,400 mph Venus: 23,000 mph Earth: 25,000 mph Mars: 11,000 mph Jupiter: 133,000 mph Saturn: 77,000 mph Uranus: 48,000 mph Neptune: 53,000 mph Note that escape velocity only takes gravity into account and ignores other forces. An object launched from Earth's surface or from any other planet with a substantial atmosphere at escape velocity would be quickly destroyed and slowed down by air resistance.
What may happen to a rocket which rises from the earth never attains escape velocity?
A rocket that doesn't reach "escape velocity" will be overcome by gravity and will be pulled back down to Earth. Also, rockets which go into orbit have not reached escape velocity. Escape velocity is what is needed to completely leave earth's gravity well.
How was the problem of escaping earth's gravity solved?
First you need to caluclate the escape volocity. Calculating an escape velocity 1. Determine the mass and radius of the planet you are on. For Earth, assuming that you are at sea level, the radius is 6.38x10^6 meters and the mass is 5.97x10^24 kilograms. You will need the gravitational constant (G), which is 6.67x10^-11 N m^2 kg^-2. It is recommended to use metric units. 2. Using the above data, calculate the required velocity needed to exceed the planet's gravitational force. The object must have greater energy than the planet's velocity as follows: V(escape)= squareroot[(2GM)/r] where "M" is the mass of the earth, "G" is the gravitational constant(6.67x10^-11) and "r" is the radius from the center of the planet(6.38x10^6). 3. Accelerate the mass to the escape velocity. It is optimal to accelerate it perpendicular to the ground, assuming it is level. Accelerating the mass at an angle other than 90 degrees with respect to the ground will require a greater velocity such that V(escape)=V(actual)*sin(theta), where theta is the angle between the ground and the projected acceleration vector. 4. The escape velocity of Earth comes to about 11.2 kilometers per second or 25000 miles per hour from the surface.
Which planet has the lowest orbital velocity?
Pluto is the planet that has the lowest orbital velocity relative to that of the earth. The orbital velocity of Pluto is 0.159.
Does every planet have an escape velocity?
"Escape velocity" is defined as the velocity required in order to guarantee that the object will not fall back under the influence of the planet's gravitational attraction. If it's possible to escape from a planet's gravitational attraction, then an escape velocity can be defined and calculated.
Why would escape velocity be different on a different planet?
The escape velocity is determined by the gravity of the planet which in turn is determined by the mass and size of the planet
What is the escape velocity of planet Jupiter in miles per hour?
The escape velocity of planet Jupiter is: ~133,097.71 miles per hour.
What does the term 'escape velocity' mean?
Escape velocity is what a moving body has to achieve in order not to be pulled back down to the planet. For Earth it is about 7 miles per second.
What is the escape velocity of mercury?
The planet Mercury's escape velocity is 4.3 kilometers per second. The escape velocity of the Earth is 11.2 kilometers per second.
To escape from a planet's an object muct reach a speed called the?
That would be its escape velocity.
How are the mass of the body and escape speed related?
The greater the mass of the planet, the greater will be the escape velocity.
What is the planets escape velocity per hour and per second?
It depends on the planet.
What is the escape velocity of the moon Charon?
Charon is the largest satellite of the dwarf planet Pluto and has an escape velocity of 0.36 mi/second or 1,296 miles per hour.
What is te Formula of escape velocity?
Escape velocity is given by. √2gR or √2GM/R .therefore escape velocity is directly prop. to gravity of a planet or star or any other body. More is the gravity more is the escape velocity. The escape velocity of our earth is 11.2 km/s and that of moon is 2.31 km/s
How do you beat gravity on Earth?
To overcome gravity, you must reach "Escape Velocity" to overcome gravity and escape a planet's orbit.
