what is the difference between the approximate masses in kilograms of earth and venus?

Size, Mass and Orbit: Whereas Earth has a mean radius of 6,371 km and a mass 5,972,370,000 quadrillion kg, Venus has a mean radius of about 6,052 km and a mass of 4,867,500,000 quadrillion kg. This means that Venus is roughly 0.9499 the size of Earth and 0.815 as massive.

The sun has a mass of 1.9891x1030 kg = 4.384x1030 lb = 2.192x1027 tons, or a mass 333,000 times that of the Earth. The radius of the Sun is 696,265,000 meters = 696,265 km = 432,639 mi or a radius 109 times that of the Earth. The volume of the Sun is so huge that it could hold over 1 million Earths.

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.

Uranus, the seventh and second-last planet from the Sun in our little solar system has a diameter of 50,724 km and a mass of 8.681 × 10^25 kg=14.54 M⊕. The thing is, Neptune is smaller than Uranus in size but it is more massive as Neptune is more dense in comparison to Uranus.

In fact, as the video above explains, Venus is actually an easier and less costly colonisation proposition than Mars is. ... Its gravity is also much more similar to Earth's than the gravity of Mars, which means colonists would likely experience less negative effects on their bones.

Whereas Earth rotates in about 24 hours Venus rotates in the contrary sense (retrograde rotation) in 243 days. The orbital period of Venus is 225 days so that a Venus year takes less than a full day.

The answer to this question lies within the difference between mass and weight. Mass is a measure of how much matter an object contains, while weight is a measure of the force of gravity on the object. ... For example, a person with a mass of 70 kg on Earth has a mass of 70 kg in space as well as on the moon.

The diameter of Venus is 12,103 km, while the diameter of the Sun is 1.4 million km. In other words, the Sun is 115 times larger than Venus. You could fit about 1.5 million planets the size of Venus inside the Sun.

In terms of size, Venus is almost a twin planet of Earth. Its diameter is 12,104 km, which is 95% the diameter of Earth. Mars is much smaller, with a diameter of only 6,792 km. And again, in terms of mass, Venus is almost Earth's twin.

Related units One newton equals one kilogram metre per second squared. Therefore, the unit metre per second squared is equivalent to newton per kilogram, N·kg−1, or N/kg. Thus, the Earth's gravitational field (near ground level) can be quoted as 9.8 metres per second squared, or the equivalent 9.8 N/kg.

The weight of an object is the gravitational force between the object and the earth. Mass is a property of the object and does not change from place to place whereas weight changes with the change in acceleration to due gravity (g). Thus an object having a weight of 98 N has a mass of 10 kg.

Physical characteristics The interior of Venus is made of a metallic iron core that's roughly 2,400 miles (6,000 km) wide. Venus' molten rocky mantle is roughly 1,200 miles (3,000 km) thick. Venus' crust is mostly basalt, and is estimated to be 6 to 12 miles (10 to 20 km) thick, on average.

The gravitational attraction between the Earth and Mars is 8.7 x 1016 N. The distance between the two planets is 5.5 x 1010m.

Venus is often named as Earth's twin because both worlds share a similar size, surface composition and have an atmosphere with a complex weather system. Both planets have almost the same size and density and Venus is only a 30% closer to the Sun than Earth. ...

Venus's mean radius is 6,051.8 km (3,760.4 miles), or about 95 percent of Earth's at the Equator, while its mass is 4.87 × 1024 kg, or 81.5 percent that of Earth.

With a radius of 3,760 miles (6,052 kilometers), Venus is roughly the same size as Earth — just slightly smaller. From an average distance of 67 million miles (108 million kilometers), Venus is 0.7 astronomical units away from the Sun. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth.

Mass is measured in kilograms (kg). Weight is a force due to the pull of gravity on an object. Weight is a force and so is measured in newtons (N). On earth, the downward force of gravity on a 1 kg mass is 10 N.
