Which is the hottest planet in our solar system?
538711
Venus is the hottest planet, with the maximum surface temp. of 900 degrees F.\nreason\nthe component of the atmosphere is carbon dioxide, which traps heat in a greenhouse effect far stronger that that of the earth.\n\nmercury has a max temp of 800 in sunlight and -270 on the dark side\n reason. sudden changes of temp is caused by the planets atmosphere is almost nonexistent. it consists only of minute amounts of helium and hydrogen

I'll assume you meant "in the solar system"\n\n -  "pluto" isn't a planet! It's just a big block of dirty ice...\n\n -  The biggest planet is Jupiter, and is made of gas.\n\n -  The smallest would be mercury, which is right next to the sun.\n\n -  It would be hard to say which planet is "medem", since there are really big planets (the gas giants: Jupiter, Saturn, Uranus, and Neptune), and really small ones: (the inner planets: Mercury, Venus, the Earth and Moon, and Mars)

in our solar system: 9\n\neven though larger bodies exist in our solar system, we're too used to having 9 planets to ever change.

Venus is the brightest object in our sky, after the sun and moon. Swirling clouds of sulphuric acid obscure Venus’s surface and inhibited study of the planet from earth until technology permitted space vehicles, outfitted with probes, to visit it. The probes determined that Venus is the hottest of the planets, with a surface temperature of about 462° C (864° F). Scientists believe a greenhouse effect causes the extreme temperature, the planet’s thick clouds and dense atmosphere trapping energy from the sun. So, Venus Have a high surface temperature.

No other planets are habitable for humans.\n\nMercury and Venus being far too hot.\n\nJupiter, Saturn and Neptune for being gas giants and so has no solid surface. The gravitational pull of these planets would crush our bodies. Juipters gravititational pull is over 300 times the earth.\n\nPluto is too far away thus seeing temperatures of over -200 degrees C.\n\nMars would have been a perfect candidate, as the temperature is quite similar to earth's at occasion. But our lifes need plenty of water and the abundance of water on Mars is basically zero.\n\nFor other life than humans, a moon called Europa, which orbits Saturn, contains frozen methane and water, which could harbour life. The only problem is its a moon and not a planet.\n\nThere are all the other planets (approximately 250 so far discovered) in the Keiper Belt which need to be examined

There are two main types of planets: the rocky planets (Mercury, Venus, Earth, Mars) and the gas giants (Jupiter, Saturn, Neptune, Uranus).  Rocky planets are also called terrestrial planets, and gas giants are also known as Jovians.  Pluto is sometimes classified as an icy planet, although its status as a planet (or a lost comet/moon) is disputed.

The sun is a big fire at the center of the of the solar system. The planets are balls that float around the sun. if the planet is to close to the sun nothing can live on it, It is too hot. If the planet is to far away from the sun nothing can live on it, it is too cold. On earth it is just right. Our atmosphere protects us from all the other stuff floating around. a meteorite is a rock that would hit the earth if our atmosphere did not protect us. the moon is a ball floating around a planet. Our moon is called "Luna" it has no atmosphere and lots of meteors hit it.

If you are talking about the sun's surface, then the earth's core is hotter than it, because the earth's core is 15,000 C while the sun's surface is 5,000 C only. But if you compare the earth's core with the sun's core, then the sun's core temperature is estimated to be 14,000,000 C - 15,000,000 C.

The Sun is the closest star to Earth.\nThe sun is a huge mass of hot glowing gas.\nAt its visible surface the heat is over 5500*C  i.e. 10,000*F.\nInside calculations showed that its temperature is about 15 million degree C.  i.e. about 27 million degree F.

By your criteria, Mercury, Venus, Mars, Saturn, Jupiter, Neptune, and Uranus are not planets.\n\nMercury has no atmosphere and therefore no weather or vegetation.\nVenus has no vegetation.  It's 900 degrees on the surface!\nMars has no vegetation, no liquid, and no magnetic field.\nSaturn & Jupiter are gas giants and have no vegetation.\nNeptune and Uranus are mostly gas and do not have vegetation.\n\nThus, by your criteria, Earth is the only planet.\n\nI did not consider "internal plumbing" because the term is too vague.

Two reports that may be new evidence.  Gathered in the\n   flight of the Ark around the entire system.  The one point is\n   it is not hot as we know of hot.  That would be igneous and\n   would react through tunneling into the surface.  The center\n    is a similar but cold material, sort of the co2 type of material.\n    Like hot it is outside of our ability to touch, without data our\n    mind cannot concept it and we could hurt our nerves.  The\n    nearby area is also unknown, that is the radiant, reactives,\n    radiological materials that are emitted into space pass through\n    nearly every material without any noticeable change.  This\n    unknown is called the central web iron.  That material is also\n    undefined because there are no samples on the surface to\n    see, or measure.  The general core is magnesium sulfates\n    these have the properties that make the planet warm, sweet,\n    and vegetative.

Venus rotates clockwise (as seen from Earth) in retrogate rotation as well as Uranus and Pluto. However, it is the only terrestrial planet that rotates in the opposite direction. The theory is that a large asteroid impacted it and that reversed its motion. As a result, it orbits the Sun faster than it rotates, creating a hostle environment with hot surface temperature, making it the hottest planet in the solar system, (hotter than Mercury, although it is closer to the Sun).
