How did Copernicus realize that Venus is an inferior planet?
it was know in ancient times that Venus passes between the Earth and the Sun, and Copernicus had a model which had the Sun at the centre, so in his model Venus was closer to the centre, thus an inferior planet by definition.

What did Copernicus realize that Venus is an inferior planet?
The Ptolemaic system has Venus travelling between Earth and Sun. Copernicus's theory has both the Earth and Venus going round the Sun although Venus is in a smaller orbit than the Earth. That makes it an inferior planet, which goes through inferior conjunction once in every synodic period, at which time it is liable to transit across the Sun's disk, as last happened in 2012. When Venus is close to passing between us and the Sun it appears as a crescent, like a crescent moon, and this is predicted by both the Geocentric and the Heliocentric theories. The main geocentric theory fails to predict Venus's gibbous phase when it is on the opposite side of the Sun. However this does not prove the heliocentric theory because Tycho Brahe's system predicts the gibbous phase for Venus yet it still has the Earth at the centre. The heliocentric theory was finally accepted long after the time of Copernicus, Tycho and even Galileo, when further scientific discoveries by Kepler and Newton, and others, made its acceptance inevitable.
What is the classification of Venus?
Venus is classified as a terrestrial planet because it is similar in size and composition to Earth. It is also classified as an inferior planet because its orbit is closer to the Sun than Earth's orbit.
Why is mercury and venus considered inferior planets?
Mercury and Venus are considered inferior planets because their orbits lie within the Earth's orbit around the Sun. As a result, they are always located relatively close to the Sun in the sky and never appear opposite the Sun in Earth's sky. This proximity to the Sun limits the viewing opportunities and visibility of these planets from Earth.

When did Copernicus realize that Venus is an inferior planet?
it was know in ancient times that Venus passes between the Earth and the Sun, and Copernicus had a model which had the Sun at the centre, so in his model Venus was closer to the centre, thus an inferior planet by definition. That was in about 1560.
Is Jupiter an inferior planet?
No. It is a superior planet. Only Mercury and Venus are inferior.
Is earth farther from the sun than venus?
Yes. Venus is the second planet, and Earth is the third planet. Technically, Venus is said to have an inferior orbit to Earth.

How many inferior planets are there?
There are two. They are Mercury and Venus. (An inferior planet is simply one that is closer to the Sun than Earth is.)
Which of these was not a contribution of Copernicus?
Which is not a contribution of Copernicus? A) The Sun lies at the center of the solar system. B) Mars will retrograde when we overtake it near opposition. C) Planetary orbits are elliptical in shape. D) Venus retrogrades when she overtakes us at inferior conjunction. E) The approximate spacing of the planet orbits away from the sun.

Venus is classified as a terrestrial planet because it is similar in size and composition to Earth. It is also classified as an inferior planet because its orbit is closer to the Sun than Earth's orbit.

According to Copernicus what planet are located between the sun and the earth?
All the theories have Mercury and Venus between the Earth and the Sun.
What planet is brightest in the night sky?
Venus is definitely the brightest but not every night. It's very bright in the evening sky when it is approaching inferior conjunction, the point at which it passes between the Earth and the Sun. Venus can also be seen in the morning sky after inferior conjunction. In the few weeks either side of inferior conjunction it can't be seen. The next inferior conjunction is coming up so look out for Venus from the end of September 2013 onwards in the evening sky after sunset, then you can check its progress until mid-December. But when it happens at this time of year Venus is quite low down in the south west or west after sunset. Inferior conjunction is on January 11 2014. From about mid-February Venus will be quite high in the south east before sunrise.
