Mercury has less mass than Earth does, and gravity varies in direct proportion to mass.
Mercury, Venus, and Mars.
No, it has much less mass.
Mercury has the smallest mass of the 8 planets at 5.5% of the mass of the Earth. It therefore has the least gravity of all the planets.
Mars, the second-smallest planet, has a diameter of just 6,788 km and the smallest planet, Mercury, has a diameter of 4,880 km, less than 2,000 km smaller than Mars. So it would take 1.34 mercury's to equal the diameter of Mars.
While Mercury is denser than Mars it is also smaller, making it less massive.
Why does Mercury and Mars have less gravity than Earth because they both have less mass than does the Earth.
Mercury has less mass than Earth does, and gravity varies in direct proportion to mass.
Well, honey, gravity ain't picky - it's the same everywhere! Both Mars and Mercury have gravity, but Mars is a bit heavier with about 0.38 times the gravity of Earth, while Mercury is even lighter with about 0.38 times the gravity of Earth. So, technically, they're both playing in the same gravity sandbox, just with different sized buckets.
The planets that have less mass than Earth are Mercury, Mars and Venus. The planets that have a lower average density than Earth are all of them; Earth is the most dense planet in our solar system.
Mercury, Venus, Mars
Actually, the idea that Pluto had about the same mass as Mars is outdated. It is now known that Pluto has less than 2% the mass of Mars, and therefore has less gravity.
Mercury, Venus, and Mars.
No, it has much less mass.
Yes there is. Its mass is about 5.5% of the earth's mass.
All of them except Mercury, Venus, and Mars.
Mercury has the smallest mass of the 8 planets at 5.5% of the mass of the Earth. It therefore has the least gravity of all the planets.
