None of them are all that close! Mars would perhaps be as good as it gets, but stay away from all planets farther away than ours unless you love sulfur clouds and acid rain so strong on Venus that it would melt anything that enters it.
Jupiter, if you're talking about our solar system's sun.
Jupiter
While Mars, Venus and Mercury are all nearer to Earth than Jupiter, they are all rocky planets.
Venus. It is sometimes called Earths twin planet due to it being a similar size and composition. It is also the planet that comes closest to ours. Although Mercury is the closest planet to the sun, it is only the second hottest planet after Venus. Venus gets hotter as the thick carbon Dioxide atmosphere holds the heat more effectively, while Mercury has no atmosphere.
APPERANTLY it has an atmosphere similar to Earths, with flecks of gold. It is like a very gold kinda coated planet... ^_^
Mercury, even though the closest planet to the sun, isn't the hottest planet because of the thing it lacks and that most planets have, an atmosphere. Venus is the hottest planet, the reason?... Venus's atmosphere. What makes its atmosphere special? It is 92 times as dense as Earths atmosphere and consists of 98% carbon dioxide. These properties make Venus's atmosphere like a magnifying glass that has the same diameter as the sun and the magnification power of an electron microscope, and a heat blanket that is so ridiculous that there isn't even a simile for it.
Venus is the hottest planet. Although it is only the second closest to the sun, its thick Carbon Dioxide atmosphere causes it to have a severe runaway greenhouse effect. Mercury is the closest planet to the sun, but it has no atmosphere therefore more of the suns light is reflected back out into space.
Venus is closest to the Earths size and mass - often referred to as Earths sister or twin planet. Venus' Mass is around 82% of Earths, while its diameter is a little smaller than Earths at around 95% of Earths.
Venus is closest to earths planet size.
Venus.
Mars
Venus is closest to the Earths size and mass - often referred to as Earths sister or twin planet. Its also the planet that gets closest to Earth, the next one orbiting inside earths orbit.
Closest to the earths serfus.
The part of the earth's atmosphere that is closest to its surface is known as the troposphere.
Venus
Uranus
Mercury, the known planet that orbits closest to the sun, has no atmosphere.
Mercury
Venus. It is sometimes called Earths twin planet due to it being a similar size and composition. It is also the planet that comes closest to ours. Although Mercury is the closest planet to the sun, it is only the second hottest planet after Venus. Venus gets hotter as the thick carbon Dioxide atmosphere holds the heat more effectively, while Mercury has no atmosphere.
Mercury is the closest planet to the Sun and has a very small atmosphere.
