Mars, although Mercury is a very close second.
Mercury is the smallest of the 8 major planets, and has the least mass. However, it is dense, and its smaller size means that it has slightly higher gravity *at its surface* than Mars does, even though Mars has about twice the mass of Mercury.
Mars = 0.376 g (Earth gravity)
Mercury = 0.38 g (Earth gravity)
* Previously, Pluto had the smallest size and lowest surface gravity. But it is now classified with other dwarf planets and distant planetary bodies, which so far are all smaller than Mercury.

∙ 15y agoMars, if you weigh 100lbs on Earth, you would weigh 37.7lbs on Mars. It would be Pluto as you would only weigh 6.7lbs on Pluto but it is no longer classed as a planet.

∙ 12y agoIf we're talking gravitational pull, then Mercury has the lowest value out of all eight planets with 38% that of earths pull at the surface.

A star has a planet held in orbit by gravitational attraction If the distance between the star and the planet were 3 times as great what effect would this have on their gravitational attraction for?
The gravitational attraction would b 9 times weaker because gravity is dependent on the inverse square of the distance.
Which planet has the GREATEST attraction to the sun?
The planet that has the greatest attraction to the sun is Mercury because of its close proximity. It experiences the strongest gravitational pull from the Sun.
What planet in your solar system has the least attraction to the sun?
Venus actually has a harsher climate than Mercury even though it is further from the sun, and it is surrounded by clouds of CO2 and sulphur. Mercury also probably has ice while venus probably does not. Therefore venus is probably the least hospitable.
A star has a planet held in orbit by gravitational attraction if the mnass of the star were doubled what effect would this have on the gravitational attraction between the star and its planet?
Double the mass means double the attraction in this case.Double the mass means double the attraction in this case.Double the mass means double the attraction in this case.Double the mass means double the attraction in this case.
Everything attracted towards the center of earth but gravity is zero at the center of earth.why?
There is nothing special about the center of the Earth itself; the attraction is in that direction, due to the accumulated effect of the attraction from different parts of the Earth. At the center of the Earth itself, the gravitational attraction towards the left, for example, by some pieces of planet Earth, would be exactly compensated by gravitational attraction towards the right, by other pieces of the planet.

What would cause the gravitational attraction between a star and a planet increased?
Huh?
What planet in solar system having strongest gravitational attraction on its surface?
Jupiter
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.

How does the gravity of the planets vary with he mass?
The gravitational field (gravitational attraction per unit mass) at any given distance is directly proportional to the planet's mass.The gravitational field at the planet's SURFACE also depends on the planet's radius.
What keeps plantes in motion around the sun?
The gravitational attraction, between the Sun and the planet.
How do planetesimals turn into a planet?
Their gravitational attraction draws in more material so that they grow by agglomeration.
How gravitational contraction occur in planet Jupiter?
It occurs in the same way as everywhere else. The greater the mass the more powerful the gravitational attraction.
Why didnt a planet form where the asteroid belt is?
Because of gravitational effects from Jupiter.
