Yes it is.
I don't know anyone who calls it that, because it's not really much like Earth. If there's any planet that's usually regarded as Earth's "twin", it would be Venus, which is almost the same size. Mars is significantly smaller.
Mars. Apart from the Moon and Venus, Mars is the closest celestial object to the Earth, it has been called Earth's 'twin' planet. Neptune and Saturn are both gas giants farther on out in the solar system.
Mars is similar in size to Earth, and they were both created during the formation of the Solar System. Their orbits are also close to each other.
Venus and Mars are often called Earth's twins because they are rocky planets like Earth, but they have different environments. Venus has a thick toxic atmosphere, while Mars has a thin atmosphere with extreme temperatures.
Remus, the son of Mars, was killed by his twin brother Romulus.
The Twin Of The Earth Is Venus ..
Because it is the planet most similar to Earth. It is also the easiest since Venus is far too hot and can't possibly contain life, researchers have tried Mars. Mars is supposedly the Earth's twin planet. Because of the deep dried out riverbeds seen on Mars' surface and the ice on the poles, it seemed very likely that life was possible on Mars.
The planet similar in size to Earth is Mars.
You might think that Mars is a near-twin of Earth, but it has a diameter of about half the Earth, measuring only 6,800 km across.
earth is 1 planet away from mars
Mars does not orbit the Earth. Mars orbits the Sun, as does the Earth.
no mars is not saver then earth
