Which planet is the hottest
Neptune is so far from the sun, at a distance of roughly 2. It is a volatile planet, with a rapid rotation of 16 hrs to one Earth day, and has intense gusting winds which whip through its gaseous atmosphere. Because of this, and its frigid temperatures, Neptune cannot sustain life as we know it.
As the graphic shows, the range of temperatures within our own solar system is very large. When compared to the average temperature on Earth, the other planets can clearly be seen to be far outside our understanding of life supporting temperature ranges. However, exploration continues to determine whether or not life exists, could exist, or even once existed on these planets. Mars has long been thought to be the most viable option for sustained lifeforms. Indeed, certain parts of the Earth routinely reach these temperatures either in winter months, or year round in polar areas.
For this reason, Mars remains the most viable option for future human life, or for discovery of existing out-planetary life forms. At the present, however, definitive proof of life has yet to be discovered, and the current knowledge indicates that most planets could not sustain life as we know it due first and foremost to hostile temperatures and atmospheres. An illustration of the Solar System. Neptune has the coldest average temperature in the Solar System.
Despite being coldest to the sun, Mercury is actually cooler than Venus due to its slow rotation and thin atmosphere. The air content of carbon dioxide on the Earth is less than that of planets like Venus and Mars.
Hence, the less air content of carbon dioxide helps to moderate the Earth's temperature and is absorbed by plants during photosynthesis to produce oxygen. List of World's Space Explorations Mission. It is the first planet that is nearest to Sun. It is the second hottest planet in the Solar System but this planet has no atmosphere, thus experiences varying temperatures throughout the day.
It is the second planet nearest to the Sun but the hottest in the Solar System. It is one of the four terrestrial planets in the Solar System. It has a dense atmosphere of carbon dioxide Are you worried or stressed? Click here for Expert Advice. Comment 4. Since Venus was named after a Greek goddess, many of the areas of Venus that were discovered also have female names, but some do not.
After they named the Maxwell Mountains after James Clerk Maxwell, the Scottish physicist, it was agreed that from that point on, all new areas of Venus would have female names. This missions to Venus have been great lessons in what happens when a planet has a high carbon dioxide level in the atmosphere and is being used today by scientists as they study our own planet in the concept of global warming and greenhouse gas effects.

The magnetic field of Venus is 0. If viewed from above, Venus rotates on its axis in a direction that's the opposite of most planets'. That means on Venus, the sun would appear to rise in the west and set in the east.
On Earth, the sun appears to rise in the east and set in the west. The Venusian year — the time it takes to orbit the sun — is about Earth days long. Normally, that would mean that days on Venus would be longer than years.
However, because of Venus' curious retrograde rotation, the time from one sunrise to the next is only about Earth days long. The last time we saw Venus transit in front of the sun was in , and the next time will be in The very top layer of Venus' clouds zips around the planet every four Earth days, propelled by hurricane-force winds traveling roughly mph kph. This superrotation of the planet's atmosphere, some 60 times faster than Venus itself rotates, may be one of Venus' biggest mysteries.
The clouds also carry signs of meteorological events known as gravity waves , caused when winds blow over geological features, causing rises and falls in the layers of air. The winds at the planet's surface are much slower, estimated to be just a few miles per hour. Unusual stripes in the upper clouds of Venus are dubbed "blue absorbers" or "ultraviolet absorbers" because they strongly absorb light in the blue and ultraviolet wavelengths.
These are soaking up a huge amount of energy — nearly half of the total solar energy the planet absorbs. As such, they seem to play a major role in keeping Venus as hellish as it is. Their exact composition remains uncertain; Some scientists suggest it could even be life , although many things would need to be ruled out before that conclusion is accepted. The Venus Express spacecraft, a European Space Agency mission that operated between and , found evidence of lightning on the planet, which formed within clouds of sulfuric acid, unlike Earth's lightning, which forms in clouds of water.
Venus' lightning is unique in the solar system. The lightning is of particular interest to scientists because it's possible that electrical discharges from lightning could help form the molecules needed to jumpstart life, which is what some scientists believe happened on Earth.
