The sidereal day is about 243 Earth days. That is the time for the planet to
rotate once .
The solar day is 117 Earth days,roughly. That is a big difference. On Earth
the difference between these two days is only about 4 minutes.
The reason for the big difference on Venus is that Venus rotates very slowly.
The solar day depends on the rotation of a planet AND its orbital motion.
The slow rotation makes the effect of the orbital motion much greater on
the length of the solar day.
Incidentally Venus rotates in the opposite direction to Earth. That's why
the solar day is shorter than the sidereal day. On Earth it's the other
Venus and Earth have sort of the same size. That is why Venus is also known as the Earth's twin sister. But actually, Venus' diameter is 12,104 km, while Earth's is 12,756 kilometers.
So, there's little difference, but Venus is a bit smaller.
It is slightly smaller than Earth.
The diameter of Venus is about 0.949 times that of Earth.
Vennie and Vanilla are the two nicknames I know of.
Venus has a revolution period that's equal to 224.7 Earth days.
The US has a total area of about 9, 826,675 square kilometers, France has about 674,843 square kilometers. Dividing the US's by France's give you a quotient of about 14.56.
So, the US is around fourteen and a half times largerthan France.
Both are named after Roman gods/goddesses.
The inner planets are rocky, loaded with minerals, and are fairly warm.
The outer planets are all gas giants . . . they are made of substances not much different than our clouds. They are very, very cold.
There are two days out of the whole year when day and night are just about the same length: 12 hours. These days are called equinoxes because the direct sunlight rays move toward the equator, making the sunlight about equal in both the Northern and Southern Hemispheres. The Fall (autumnal) equinox for the Northern Hemisphere is September 21 or 22, and the Spring Equinox is March 20. In the Southern Hemisphere, the names are reversed for the two days.
Because of the apparent width of the solar disc, the days at the equinoxes are still slightly longer than the night. The parity of day and night occurs the day before the vernal equinox, and the day after the autumnal equinox.
Because of it's thick CO2 atmosphere and slow rotation, Venus maintains an average temperature of around 460 °C (860 °F) whether it is "day" or "night". :)

the purpose for earth day is to help save the earth
mmm... maybe a good slogan for Venus is..., well almost everyone say Venus was just like the earth, its almost the same size, and its the clothes to the earth, and it was like earth, you can say " Travel to Venus to see the earth twin sister "
hpe you like it;D
The consensus among anthropologists is that she is a cult figure, probably representing fertility. Others suggest that she was the equivalent of today's skin mag or porn site. See http://willendorf.org/ for a more complete discussion.
There have been many space probes to Venus. Here are a few important ones: * Mariner 10 (NASA) * The Venera series of probes (Roscosmos) * Magellan (NASA) * Venus Express (ESA) (check related link)
Practical Answer If the distance between Earth and Venus is to be maximum, then the two planets would have to be on opposite sides of the Sun. There would be no way to send radio waves to Venus in this situation as the waves cannot travel through the Sun. So, in reality, this question has no answer.
Theoretical Answer For the sake of curiosity, lets assume the waves travel through the Sun in a straight line.: Earth's average distance from the sun = 93,000,000 miles Venus' average distance from the sun = 67,200,000 miles Max separation (opposite directions from the sun) = 160,200,000 miles Speed of radio (light) = 186,282 mi/sec Time for a radio or radar return = 2 x (160,200,000 / 186,282) = 1,720 seconds = 28-2/3 minutes(rounded)
Saturn's equatorial radius is about 37,457 miles.
venus because its similar to earth by size, mass, and density But there the similarities end. Venus has no oceans, also Venus is covered by thick, rapidly spinning clouds that trap surface heat, creating a scorched greenhouse-like world with temperatures hot enough to melt lead and pressure so intense that standing on Venus would feel like the pressure felt 900 meters deep in Earth's oceans. These clouds reflect sunlight in addition to trapping heat. Because Venus reflects so much sunlight, it is usually the brightest planet in the night sky.
The single most important thing is that despite the systematic murder of six millioin of their people, the Jews remained united and did not fall away into the corners of the earth.
Venus is the Roman equivalent of the Greek goddess Aphrodite. She is the goddess of love and beauty.
Answer2: Aphrodite (Roman Venus), the goddess of fertility and love, considered to be the "sister of the Assyro-Babylonian Ishtar and the Syro-Phoenician Astarte" (Greek Mythology, by P.
In Colonial America, there were only thirteen American colonies at the time that the Revolutionary Movement began simply because only that many had thus far been organized. It should be noted that there were, at the time, numerous other British colonies throughout the Americas, both to the north and to the south of what would soon become the (thirteen) United States of America.
An apparent or solar day on Venus is 116.75 days (this is not the same as its rotational period relative to the background stars, which is 243 days).
The planets move through all the signs of the zodiac. So, at times Venus is in Aquarius.
Wisconsin Senator Gaylord Nelson created the idea for Earth Day.
Yes, robots have landed on Venus, but due to the extreme conditions on the planet's surface, their operational lifetimes have been very short. Venus is a hostile environment with extremely high temperatures, crushing atmospheric pressure, and corrosive clouds of sulfuric acid. As a result, any lander sent to Venus faces significant challenges in terms of design and durability.
Here are a few notable robotic missions that have successfully landed on Venus:
Venera Series (Soviet Union): The Soviet Union's Venera program was the first to successfully land spacecraft on Venus. The Venera landers and probes were designed to withstand the harsh conditions. The first successful landing was Venera 7 in 1970, which transmitted data back to Earth for about 23 minutes before succumbing to the extreme environment. Subsequent missions like Venera 9, Venera 10, and Venera 13 also sent back images and data from the surface.
Vega Program (Soviet Union): The Vega program, also conducted by the Soviet Union, sent two spacecraft, Vega 1 and Vega 2, to study Venus along with Halley's Comet. Each spacecraft had a lander component designed to transmit data from the Venusian surface. The landers were equipped with special protection to survive the challenging environment.
Akatsuki (Japan): Akatsuki, also known as the Venus Climate Orbiter, is a Japanese space probe that was successfully inserted into Venus's orbit in 2015 after a previous failed attempt. While not a lander, Akatsuki has been studying Venus's atmosphere and weather patterns from orbit.
Venera-D (Proposed): The Venera-D mission is a proposed Russian mission intended to further study Venus. It's planned to include an orbiter, a lander, and a long-duration surface station to better understand the planet's geology, atmosphere, and environment.
Due to the extreme challenges presented by Venus's conditions, designing landers that can survive and function for extended periods on its surface remains a significant engineering feat.
