what are the similarities of venus earth and mars?
9859
Venus compared to Earth. Venus, Mars and Earth, three out of the four inner or 'rocky' planets of the Solar System, have a lot in common – a solid surface you could walk on, a comparable surface composition, an atmosphere and a weather system.

Terrestrial and Jovian Planets They are rocky with a dense metal core consisting mostly of iron. Planetary scientists theorize that Mars and Venus may once have had conditions like Earth's, favorable to life.

Often called Earth's sister planet, Venus is the closest in size, with a mass of more than 80 percent that of our planet and a diameter of only a few miles less.

Mercury, Venus, Earth, and Mars are the planets closest to the Sun. They are called the inner planets. The inner planets are made up mostly of rock. The outer planets are Jupiter, Saturn, Uranus, and Neptune.

['A day on Venus lasts longer than a year. ... ', 'Venus rotates in the opposite direction to most other planets. ... ', 'Venus is the second brightest object in the night sky. ... ', "Atmospheric pressure on Venus is 92 times greater than the Earth's."]

Common sense would say the answer is either Mars or Venus, our next door neighbors. Of the two, Venus comes closer to the Earth than any other planet and its orbit is closest to ours. ... They let the planets orbit for thousands of simulated years, all the while calculating the distance between any two of them.

The greenhouse effect determines the flow of energy arriving at and leaving from Earth. ... Venus is similar to Earth in terms of size and mass, but its surface temperature is about 460 degrees Celsius. This is hot enough to melt lead! The Venusian atmosphere is mainly made up of carbon dioxide, a greenhouse gas.

Whereas the Earth has an average surface temperature of 14 degrees Celsius, the average temperature of Venus is 460 degrees Celsius. That is roughly 410 degrees hotter than the hottest deserts on our planet.

Venus in the Solar System However, Venus has a much more massive atmosphere than its terrestrial sibling, with a surface pressure about 90 times higher and a composition predominantly of carbon dioxide, which is a minor constituent on the Earth.

Venus 101 Named after the ancient Roman goddess of beauty, Venus is known for its exceptional brightness. Find out about the volcanoes that dot Venus's surface, the storms that rage in its atmosphere, and the surprising feature that makes Venus outshine every planet or star in the night sky.

After all, Earth isn't the only planet in the Sun's Goldilocks Zone - Venus and Mars are also in this habitable zone, but aren't currently habitable. "Venus is Earth's sister planet, both are about the same size and in the same region of the solar system, and Venus once also had water," Professor Webb said.

Two nearlyidentical spacecraft around Mars and Venus have compared the two worlds'atmospheres and found them to be surprisingly similar. ... Both Venus's and Mars's atmospheres are about 95 percentcarbon dioxide. Earth's is mostly nitrogen now, but scientists think it used tobe more like the other rocky worlds.

Size and Distance With a radius of 3,760 miles (6,052 kilometers), Venus is roughly the same size as Earth — just slightly smaller.

Venus's atmosphere is 93 times heaver than Earth's, the air is mostly carbon dioxide, the planet is covered in sulfur dioxide clouds,and ground temperatures reach 860 degrees. And yet lightning works exactly the same way on both planets.

both have 95%of carbon dioxide. Both are rocky worlds with a CO2 atmosphere. Both lie within our sun's habitable zone. Venus is about the size of Earth, while Mars has the same surface area as that of the earth's dry land.

In Roman mythology, Venus was the goddess of love, sex, beauty, and fertility. She was the Roman counterpart to the Greek Aphrodite.

Mars is much smaller, with a diameter of only 6,792 km. And again, in terms of mass, Venus is almost Earth's twin. It has 81% the mass of Earth, while Mars only has 10% the mass of Earth. The climates of Mars and Venus are very different, and very different from Earth as well.
