Answer #1:

Mecury and Mars, because Mecury has 38% and Mars has 38%, so Mecury

and Mars it is.

=========================

Answer #2:

ALL planets "have gravity". So do all stars, comets, asteroids, meteoroids, stones,

raindrops, people, dogs, and snowflakes. Everything with mass "has gravity".

Earth ble and green planet, Mars as the close planet viable for life .Neptune, Saturn, Jupiter, Mercury, Venus,and Pluto though now astronomers debate whether planet .Jupitar and neptune are gas giants assumed inhabitable. perhaps you are asking since know of planet in Milky Way Galaxy or are from the earth type planet astronomers were said to have discovered via Hubble telecope in 2000 or 1999. an article in the news described this. similiar claims were made back in 1964 whafter mission to the moon and in the 1970's as well. in 19th century also .Even Galileo ,Copernicus and Johan Keplar might have made similiar claims.search for extraterrestrial life and astronomer magazine 1995 issue might have it perhaps September issues not sure got it from a libraryso unsure of date

Mercury and Mars have nearly identical gravities, and as a result, your weight would be similar on both planets.

Venus and Earth are similar because of their same sizes and almost same gravity.

Two planets with simarlar mass and size are?

Uranus and Neptune have similar mass and size. Venus and Earth are actually not as close in terms of mass. Neptune is the heavier of the two gas giants, the ratio of their masses is 0.87, while the mass ratio of Venus to Earth is only 0.82.

What two planets are close in size?

Venus and Earth are similar in size. Uranus and Neptune are also of a similar size, but both much larger than Earth and Venus.


What are two ways Earth and Venus are similar?

• an atmosphere (though with different chemicals in them) • CO2 • a surface (they're terrestrial planets) • mass (though their masses are different) • volcanoes • greenhouse effect • craters


Is there anything similar in mass and volume?

Density is a quantity shared by objects with mass and volume. Volume is the ratio of density to mass, whereas mass is the product of volume and density. Earth and Venus are two planets with similar mass and volume. Venus is slightly smaller.


Two planets with similar mass and size are?

Venus and Earth are similar in size and density. Venus is only a little smaller and lighter, and both have similar gravity. This is why Venus is sometimes called 'Earth's Twin.' However, Venus has an atmosphere 100 times thicker than Earth and surface temperatures that are extremely hot. Venus has no life or water as Earth does.


Which has a more powerful gravity a small planet or a large planet?

It would depend on the mass of the planets. The surface gravity of a planet is directly proportional to its mass and inversely proportional to the square of its radius. If two planets have the same mass but different sizes, the smaller planet will have stronger gravity because the surface is closer to the center of mass. Conversely, if two planets are of the same size, the one with more mass will have stronger gravity. Since larger planets usually have more mass than smaller ones they usually have stronger gravity, though not always.


Which two planets are similar in composition?

Neptune and Uranus
