Although astronomers in ancient times believed the bright objects that appeared sometimes in the morning sky and sometimes at night were two different objects, Pythagoras was the first to suggest that it was only one celestial object.
Being the second planet from the sun, Venus has a high surface temperature and an atmospheric pressure that is over 90 times that of the Earth’s. There are some similarities between the Earth and Venus, however, including their similar relative sizes and the fact that they both have a core, mantle and crust.Learn more about Planets

The eight described planets all orbit the Sun at different distances; Mercury is the closest planet to the sun, followed by Venus, then Earth, Mars, Jupiter, Saturn, Uranus and Neptune. The distances of the planets are normally measured in kilometers, because scientists use metric measurements. However, scientists also use a unit called an “astronomical unit,” which is equal to the distance between Earth and the sun.Full Answer >
Venus is the brightest planet in the night sky. It is the second-brightest object visible to the naked eye after the moon and is visible in the hours just before sunrise and after sunset. These hours of visibility are due to the planet's proximity to the sun.Full Answer >
