What is the mass of planet Venus?
4.867 × 10^24 kg (0.815 M⊕)
What is the size of Venus diameter?
Is Venus big or small?
Venus is actually only a little bit smaller than our home planet, with a mass about 80% of Earth’s. 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.
How much larger is Earth than 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.
Does Venus have land mass?
Venus is a volcanic planet, with about four-fifths of the planet covered by smooth, lava-hardened plains. The surface has few impact craters, indicating that it is relatively young. The planet’s surface area is 90 percent that of Earth’s, covering 178 million square miles (460 million square km).
What is Venus’s size and temperature?
Venus’s upper atmosphere extends from the fringes of space down to about 100 km (60 miles) above the surface. There the temperature varies considerably, reaching a maximum of about 300–310 kelvins (K; 80–98 °F, 27–37 °C) in the daytime and dropping to a minimum of 100–130 K (−280 to −226 °F, −173 to −143 °C) at night.
Is Venus the North Star?
The Fixed Star, or North Star, is essential for navigation in the northern hemisphere.
How is Venus and Earth similar?
Venus is sometimes called Earth’s twin because Venus and Earth are almost the same size, have about the same mass (they weigh about the same), and have a very similar composition (are made of the same material). They are also neighboring planets. Venus also rotates backwards compared to Earth and the other planets.
What’s bigger Earth or Venus?
Size and Distance The planet is nearly as big around as Earth – 7,521 miles (12,104 kilometers) across, versus 7,926 miles (12,756 kilometers) for Earth. At its nearest to Earth, Venus is some 38 million miles (about 61 million kilometers) distant.
What are Venus’s measurements?
How big is Venus? 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.
What is the size of Venus compared to other planets?
Venus is similar in size to Earth, which earned it the title of Earth’s twin. Venus has a diameter of 12,100 km and a surface area of 4.6 x 108 km2. These measurements are 95% and 90% of Earth’s diameter and surface area respectively. With a volume of 9.38 x 1011 km3, Venus’ volume is 86% of Earth’s.
What is the closest star to Earth?
Alpha Centauri: Closest Star to Earth. The closest star to Earth are three stars in the Alpha Centauri system. The two main stars are Alpha Centauri A and Alpha Centauri B, which form a binary pair. They are an average of 4.3 light-years from Earth.
How big is Venus compared to the Earth?
Density, mass, and volume. Venus is a rocky, terrestrial planet like Earth, and likely formed the same way at the same time. It has a mass of 4.87 trillion trillion kilograms, about 82 percent that of its sister planet.
What are the two land masses of Venus?
The planet boasts two land masses, Ishtar Terra and Aphrodite Terra, which make up about 8 percent of its surface area (as compared to the 25 percent of continent-covered surface on Earth).
How big is Venus and how often does it rotate?
Venus has a mean radius of 3,760 miles, or 6,052 kilometers. Most planets in the solar system, including Earth, spin so rapidly that they bulge slightly at the middle, creating a radius that differs at the poles and the equator. Not so for Venus, which only rotates once every 243 Earth days or so (and backwards,…
How big are the craters on the surface of Venus?
Venus is covered in craters, but none are smaller than 0.9 to 1.2 miles (1.5 to 2 kilometers) across. Small meteoroids burn up in the dense atmosphere, so only large meteoroids reach the surface and create impact craters.
