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.

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.
What does the earth's gravitational attraction prevent gases from doing?
The Earth's gravitational attraction prevents gasses from escaping into outer space.
Which planet has the GREATEST attraction to the sun?
Mercury has the greatest attraction to the Sun due to its proximity and mass. Being the closest planet to the Sun, the gravitational force between Mercury and the Sun is stronger than any other planet in our solar system.
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?
If the distance between the star and the planet were 3 times as great, their gravitational attraction for each other would decrease by a factor of 9 (3 squared). The force of gravity between two objects is inversely proportional to the square of the distance between their centers.

What planet in solar system having strongest gravitational attraction on its surface?
Jupiter
What would cause the gravitational attraction between a star and a planet increased?
Huh?
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.
Which planet has the GREATEST attraction to the sun?
Mercury has the greatest attraction to the Sun due to its proximity and mass. Being the closest planet to the Sun, the gravitational force between Mercury and the Sun is stronger than any other planet in our solar system.
What keeps plantes in motion around the sun?
The gravitational attraction, between the Sun and the planet.
What would be the greatest force of gravitational attraction?
The force of gravitational attraction between two objects is strongest when their masses are large and they are very close together. For example, a planet and a star or two massive celestial bodies would experience a strong gravitational attraction between them.
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?

How do planetesimals turn into a planet?
Their gravitational attraction draws in more material so that they grow by agglomeration.
