when was planet venus discovered?

Answer 1

It's visible from Earth at night with the naked eye so it has been known since ancient times. It appears as one of the brightest "stars" in the sky and is most noticeable in the early evening or early morning - it is sometimes called "The Morning Star" or "The Evening Star". Venus' orbit is shorter that the Earth's (only 225 Earth days) this means that it 'overtakes' the Earth every 584 days as it orbits the Sun. As it does so, it goes from being the 'Evening star', visible after sunset, to being the 'Morning star', visible before sunrise.

Several other planets are visible at night without the aid of telescopes - in particular Mars, Jupiter and Saturn. These planets were observed to behave differently in their movements across the sky due to the fact that they are orbiting the Sun whilst "normal stars" remain static and their apparent motion is due to the Earth's own movement. For this reason the visible planets, including Venus, were known as "Wandering Stars".

Pythagoras is usually credited with recognizing that the morning and evening stars were a single body in the 6th Century BC, although he thought that Venus orbited the Earth. In the 17th Century Galileo found that Venus showed phases like the Moon's which he correctly stated could be possible only if Venus orbited the Sun.

Answer 2

Venus has been known since prehistoric times. Its the biggest object in the sky except for the sun. The first spacecraft to visit was Mariner 2 in 1962.
Take care.

Answer 3

it has been known since ancient times. But in those times, it was known as the 'wandering star'. It wasn't until the 17th century that observations made by Galileo suggested that Venus was in an orbit around the sun.

Answer 4

the planet was discovered probably by who ever laid eyes on it first and found out it was a planet. because there probably were people that thought it was a star. so you have to search who found out it was a planet first not when it was discovered

Answer 5

Venus has been known to people for thousands of years. It was probably a caveman who first noticed "the morning star" and "the evening star."

Answer 6

Answer 7

Being between the brightest gadgets in the sky, and actual distinguishable from the "fastened" stars by utilising its action against them, Venus has been usually happening to be "no longer a famous individual" because of the fact antiquity. No "scientist" got here upon it. the comparable is going for the different vivid, bare-eye seen planets: Mercury, Mars, Jupiter, Saturn. Our word for "planet" comes from the Greek for "wanderer" -- the ancients called them that because of the fact they known their action became diverse from the stars, and that they appeared to "wander" between the stars. Galileo gets credit for being the 1st human to truly see that those "wanderers" weren't factors of light like the stars, yet had disc shapes are have been certainly different worlds like earth.
