Planet Venus
The 2nd planet from the Sun in our solar system. Excluding the moon, it is the brightest natural object in the night sky.
2,020 Questions
The surface of Venus is incredibly hot, with temperatures reaching around 900 degrees Fahrenheit (475 degrees Celsius). This extreme heat is due to the thick atmosphere of carbon dioxide that traps heat, leading to a runaway greenhouse effect on the planet.
Why do scientist need to use radar to study Venus' surface?
Scientists use radar to study Venus' surface because its thick atmosphere makes it impossible to see the surface with visible light. Radar can penetrate through the clouds and provide detailed images of the planet's surface features, allowing researchers to study its geology, topography, and other characteristics.
Why is Venus the hottest planet?
It is closest to the Sun.
Venus is the hottest planet in solar system because it has a atmosphere containing nearly 96% of CO2 a gas responsible for causing greenhouse effect (if you don't know green house effect google it) making Venus literally a oven as the heat trapped by the CO2 is not able to go out.
Venus is the hottest planet because The atmosphere consists almost entirely (96%) of carbon dioxide (CO2), a greenhouse gas responsible for the incredibly hot, greater than 400ºC conditions on Venus, surpassing the melting point of lead. The rest of the atmosphere is comprised of 3% nitrogen, 0.003% water vapor, and small quantities of other gases.
When will you be able to see Venus?
Venus is one of the brightest objects in the night sky and can be seen shortly after sunset or before sunrise depending on its position in its orbit. Venus is typically visible in the evening sky for a few hours after sunset or in the morning sky a few hours before sunrise. Its visibility also depends on your location and if there are any obstructions like tall buildings or mountains.
When was Venus discovered and by whom?
Planet Venus is one of the cosmic bodies that are easily visible without the need of the aid of any optical tool, so, it's not easy to attribute to anyone its discovery. However, we can mention the important contributions of scientists like Nicolaus Copernicus, with his Sun-centered Solar System theories; and Galileo Galilei, who observed Venus with the telescope he created herself.
Venus is named after the Roman god of love and beauty.
Venus' composition is primarily made up of a thick atmosphere of carbon dioxide, with clouds of sulfuric acid. Its surface is rocky and covered with volcanic plains, mountains, and big impact craters. Analogous to Earth, Venus also has a metal core.
What is the wind speed on Venus?
There are high-speed winds in the thinner upper cloud layers, which increase in speed in the middle layers. These winds blow from west to the east. The upper winds have a speed of around 300 km/hour, and middle layer winds (the equivalent of Earth's jet streams) move at up to 700 km/hour (435 mph). But in the thicker lower layers, this slows to only a few kilometers per hour.
For example, on October 23, 1975, the Soviet lander, Venera 10, measured a wind speed of 3.5 meters/second or about 8 mph at the surface.
What is the temperature and diameter of Venus?
The surface temperature is about 460°C planet-wide, all the time, and the diameter is slightly smaller than Earth's (12103.6 kilometers with virtually no equatorial bulge).
What is the night temperature on Venus?
The average night temperature on Venus is around 462 degrees Celsius (864 degrees Fahrenheit). This extreme heat is due to the planet's thick atmosphere, which traps heat and creates a strong greenhouse effect.
What is the gravity on Venus compared to earth?
The gravity on Venus would be about 90.4% of Earth's (0.904 g). Although the planet has a smaller mass, it also has a slightly smaller diameter.
Planets have the colors that they have because of what they are made of and how their surfaces and/or atmospheres reflect and absorb sunlight. Venus is entirely covered with a thick carbon dioxide atmosphere and sulphuric acid clouds which give it a light yellowish appearance.
Venus is very, VERY hot. Since it is only so close to the sun, it contains a lot of heat. Venus contains gravity and oxygen it is so hot that no one can live on it. The heat is about 842-895 degree's.
No, Venus is not a star. It is a planet in our solar system, the second closest planet to the Sun. Stars are massive celestial bodies that produce their own light through nuclear fusion, while planets do not produce their own light and instead reflect light from the Sun.
Venus has been known since ancient times due to its brightness and visibility in the night sky. It was observed and recorded by various civilizations, including the Babylonians, Greeks, and Romans. The first telescopic observations of Venus were made by Galileo Galilei in the early 17th century.
How many miles is Earth from Venus?
Venus is the closest planet to earth. It's only 26 million miles away from earth. In perspective to the sun, which is 93 million miles away from earth.
The distance to Venus varies because planets move relative to each other as they orbit the Sun. 26 million miles is, roughly, the nearest Venus gets to Earth. The planet Venus is about 42 million kilometers (26 million miles) from Earth at its closest point and about 258 million kilometers (160 million miles) away at its most distant point.
How long is a Venus day compared to a Venus year?
A year on Venus is how long it takes for the planet to fully orbit the sun once. A day is how long it takes the planet to completely rotate once, ie, turn all the way around. Venus rotates very slowly, and by the time it has turned one full circle, the planet has already gone all the way around the sun.
