No oxygen.
No life.
Earth's neighbors.
You might want to study this before a science test!
Both these planets have solid rocky surface like the earth but both don't have the oxygen atmosphere, water and life
Although there are a few planets similar to Earth's gravity, atmospheric pressure, temperature, size, etc. Mars is the planet that is most like Earth. Long ago, it was believed that Mars harvested water, just as Earth does now. Mars also has a little over twenty-four hour days and the rotation is much like Earth's.
they are all small rocky planets [earth,mercury,venus,mars]
-about the same size -both have atmosphere -both have volcanos -both have clouds really Venus and Earth have no similarities whatsoever, so this is the best i can do
Venus. Similar to Earth in many ways, a runaway greenhouse effect is thought responsible for its 900°F (480°C) surface temperature.
with the exception of Pluto Classed as "Dwarf Planet" the inner 4 planets Mercury, Venus , Earth and Mars are all solid planets (rocky) The planets after that are all Gaseous planets
Mars bars in the microwave
In many ways, Mars is very similar to Earth, but it's also different in many ways
There are a lot of ways to explore the solar system. Some people, like NASA, see the solar system in stars by the Hubble Telescope satellite. But that satellite only checks the Earth. In order to explore the whole solar system, you must travel to Mars, Jupiter, Saturn, Uranus, and Neptune (Pluto is not considered as a planet in the solar system in this answer). If you want, you can also explore Venus and Mercury. But you cannot land on Mercury, especially on Venus (the hottest planet in the solar system). So now astronomers/astronauts only explore Mars - Neptune.
Venus spins clockwise, while all the other planets spin counter-clock ways.
first of all its spins and venus spins in a retrograde motion or the opposite direction of the sun
1. Size 2. Distance from the Sun 3. Earth is not covered in extremely hot and deadly poisonous clouds of acid gas.
