Why Venus is the same size of earth and the same gravity?
Since Earth and Venus are roughly the same size AND have roughly the same mass, they have roughly the same gravity. The acceleration of gravity on the surface of Venus is 90.3% of what it is on Earth's surface.
How would the size of parachute required for a space probe be different on Venus which has a thick atmosphere or on Mars which has a thin atmosphere?
The atmosphere of Venus is very thick, and a parachute would have much greater drag for a given size, than on Earth or Mars. So it could be smaller to achieve the same slowing of a space probe's descent. On Mars, a larger parachute would be required, but fortunately Mars, being a smaller planet, has much less gravity than Earth, so the parachute does not have to resist the same acceleration force (which is roughly the same on Venus as on Earth).
Is the year on every planet the same as earth?
what planet has a simular year as earth
What star is the same size as the earth?
A white dwarf can be roughly the same size as Earth.
What planet's atmosphere has no air or water?
Mercury is the only major planet without an atmosphere. It is able to hold some gases close to its surface, but not really enough to call it an atmosphere. Its due to the size of the planet being so small and lack of a decent magnetic field that it is unable to sustain an atmosphere.
Is the planet Venus a gas or a rocky planet?
Venus is a 'rocky' planet, with a dense atmosphere, very roughly the same size as earth, the planet that can approach closest to the earth, and the brightest one in our sky.
Which planet has a hot atmosphere and about the same size as the earth?
venus
Which planet is considered to have the most similar atmosphere to our planet?
no planet has an atmosphere like ours! Sorry! Fun Fact: Venus is the same size and mass as Earth!
Why do the gases in the earth atmosphere stay close to the surface of the planet?
Mostly for the same reason you stay close to the surface of the planet - gravity!
Which planet have air on it?
Venus has an atmosphere, though the "air" is not the same as on Earth (and would, in fact, instantly kill you).
What planet in your solar system is considered to bee earths twin?
In our solar system the planet Venus is considered to be Earth's twin, and is roughly the same size, slightly smaller and about 4/5 of Earth's mass.
What planet is roughly the same as neptune?
Uranus
Who is the twin planet of earth and why it is called so?
Venus is called Earth's twin planet, because they have similar size and mass. They also consist of roughly the same materials and were formed around the same time almost four billion years ago.
Why doesnt the gas on a gas giant planet escape into space?
For the same reason that our atmosphere on Earth does not escape into space - gravity.
What do mars and earth have alike?
They are both "terrestrial" (rocky) planets. They both have an atmosphere. They have roughly the same land area (Mars has no oceans though). The length of a day is roughly equal on both.
What planet is the same as the planet earth?
no planet
Why Venus is the same size of earth and the same gravity?
Since Earth and Venus are roughly the same size AND have roughly the same mass, they have roughly the same gravity. The acceleration of gravity on the surface of Venus is 90.3% of what it is on Earth's surface.
