my opinion is mars
Venus.
Earth is the next planet to orbit inside Mars, while Jupiter is the next planet to orbit outside Mars orbit. Mars' orbit is closer to Venus (and Mercurys') orbit than it is to Jupiters though.
On both Venus and Mars, the most abundant gas in the atmosphere is carbon dioxide. On Earth nitrogen is the most abundant gas.
Mars and Venus would have seasons most like Earth due to their similar axial tilts and orbital patterns. Mars has a tilt of about 25 degrees, while Venus has a tilt of around 3 degrees, both contributing to distinct seasonal changes on these planets.
1) EARTH2) JUPITERSolar system:Sun-Mercury-Venus-Earth-Mars-Jupiter-Saturn-Uranus-NeptunePluto is no longer a planet.
That depends on the time of the year - or even century. Of all the planets of the Solar System, Venus approaches closest to ours. Most of the time, either Mars or Venus are closest to Earth. On rare occasions, Mercury is closer than either Mars or Venus.
The planet that most resembles Earth in many factors is Mars. However, no planet most resembles the Earth in all factors.
All the inner planets and the most related one is possibly Venus because that Venus is about the same size as earth. Many people say Venus because of the size but its Mars. If there was any other planet to survive on it would be Mars. Mars has valleys and mountains and its temperature isn't that much of a difference from Earth, or it isn't a dramatic change like Venus's. It has some oxygen and it used to have water or it does i cant remember. And scientists have found fossilized bacteria on Mars so it proves Mars can support life.
Among the known planets, Venus has the most similarities to Earth in terms of size and gravity. However, with its thick atmosphere of carbon dioxide, extreme temperatures, and lack of liquid water on its surface, Venus is not as Earth-like as Mars. Mars has a similar day length, reasonable temperatures at times, evidence of past water flow, and lower gravity compared to Earth.
Mercury is most similar to Earth's moon. Like the moon it is a rocky, airless world covered in craters.
Venus has the most carbon dioxide atmosphere of any planet in the solar system, with about 96.5% of its atmosphere composed of carbon dioxide. This thick atmosphere contributes to the planet's extreme greenhouse effect and high surface temperatures.
I don't know but im not sure.... i think its Venus or Mars Mars is by far the most Earth-like but "people" as human beings could not have evolved there.
