The second planet from the sun and Earth's closest neighbor, Venus is famously known for being the brightest object in our night sky aside from the moon. Venus is very similar to Earth both in size and in gravity levels. It is a terrestrial planet and is visible to the naked human eye.

How Did Venus Get Its Name?

The existence of Venus has been known for thousands of years. Many early astronomers noted the presence of Venus as the planet can be seen without sophisticated or advanced equipment. Venus is named for the Roman Goddess of Love.

What Color is Venus?

Although we may have images in our minds of Venus being a bright, cartoonish orange, the surface of Venus actually appears more like a soft yellow to the human eye. Many photos that are generated of Venus have some degree of color alteration in order to bring out the planet's details.

How Long is a Day and a Year on Venus?

One of the most fascinating facts about Venus is the planet's day and year length. One rotation on Venus lasts for the equivalent to 243 Earth days, which is the longest length of any planet in the Solar System! Interestingly, Venus takes 224.65 Earth days to complete a revolution around the Sun. This means that a day on Venus is technically longer than a year.

What is Venus Made Out Of?

The composition of Venus is similar to that of planet Earth. It has a rocky surface and an iron core at its center. The atmosphere of Venus is mostly made out of carbon dioxide. The planet has a very strong greenhouse effect, which results in a very high average temperature. The average temperature of Venus is 864 degress Fahrenheit (or 462 degrees Celsius). Venus is the hottest planet in the Solar System, even though Mercury is technically closer to the sun.
