no planet has an atmosphere like ours! Sorry! Fun Fact: Venus is the same size and mass as Earth!
Mars is the most similar known planet to Earth in our solar system. It is thought to have similar composition, and, maybe even water. It cannot, however, sustain life as we know it, because Mars lacks both a thick atmosphere, and an active core (therefore it also lacks a magnetosphere, so its atmosphere is ionized).
Venus is the planet that is most similar to Mars in terms of size and composition. Both planets have a similar rocky surface and a thin atmosphere. However, Venus has a much thicker atmosphere and is much closer to the Sun than Mars.
Venus is most similar in size and mass to Earth. Both planets are considered terrestrial planets and have similar compositions and densities, which is why they are often referred to as "sister planets."
Mercury is the planet that most resembles the Moon in visible surface features and atmosphere. It is a grey planet that has many craters and a thin atmosphere.
Venus is the planet most similar to Earth in size, mass, volume, and density. It is often referred to as Earth's "sister planet" due to these similarities despite having a very different atmosphere and surface conditions.
the most gaseous inner planet would be Venus, also the hottest planet
If we were going to compare any planet to the sun, it would be the gas giant Jupiter. The sun is a couple of hundred times bigger than Jupiter, but the king of the planets is the one that is more similar to the sun than any of the other planets.
Neptune is the planet that is most similar to Uranus in terms of size, composition, and atmosphere. Both planets are similar in size, composition, and are classified as ice giant planets.
The planet similar in size to Earth is Mars.
Mars
The largest planet is Jupiter, with an atmosphere made mostly of hydrogen.
