Why does Venus have phases like the moon?
You know how the moon rotates around the Earth, and has phases because of the suns rays hitting its crust? Its the same with Venus. You know that Venus revolves around the sun, right? But did you know that it also has phases? Its true. Anyway, Venus's phases are just like the moons. I don't know why Venus has phases, but I sure do know how.;)
How did Galileo discover the planet Venus's?
He did not discover the planet Jupiter. He only used his telescope to see its four largest moons. The planet is and always has been visible to the naked eye and was known to people since ancient times.
Who was the first person to see mercury with a telescope?
The first person to see Mercury with a telescope is believed to be Galileo Galilei in the early 17th century. He observed the phases of Mercury, similar to those of the Moon, which supported the heliocentric model of the solar system.
What did Galileo see when he observed Venus through his telescope?
Galileo observed phases of Venus, which were only possible if Venus orbited the Sun and not Earth, supporting the heliocentric model of the solar system proposed by Copernicus. This observation was a key piece of evidence in favor of the heliocentric theory.
How did Galileo disprove the Geocentric theory of the solar system?
Galileo's observations of the phases of Venus proved that it orbited the Sun and lent support to (but did not prove) the heliocentric model.Galileo saw the four largest moons of Jupiter in orbit around the planet, proving that the Ptolemaic system was not simpler - the solar system was not geocentric (the planets and the sun did not orbit around the earth).As far as the observations of Venus go, Galileo saw that Venus displayed phases very much like our moon. Now, according to the Ptolemaic system, Venus could only display a crescent phase because its epicycle put it always in between Earth and the sun. The Copernican system put everything rotating around the sun, and in this way it explained the phases of Venus.Think of it this way, if Venus is always in between the sun and the earth, how can we ever see it completely lit up, like a full moon? The sun is always on the other side of it, so Venus must at some point go on the other side of the sun.
What phases of venus are predicted by the ptolemaic system?
The Ptolemaic system predicts that Venus goes through phases similar to the Moon, from crescent to full. This model was proposed by the ancient Greek astronomer Ptolemy and was used to explain the varying appearances of Venus in the sky as seen from Earth.
What planets are seen in phases like the moon?
Both Mercury and Venus, being closer to the sun than us, will show phases. When Venus is at is brightest it is generally just a bit over half full. If you were on Mars, you would note phases on earth.
Can you see the phases of any planets from Earth?
Yes, some planets in our solar system, like Venus and Mars, exhibit phases when observed from Earth. These phases are caused by the changing relative positions of the planets and the Sun as viewed from Earth. Mercury and Venus can display crescent phases, while Mars can show gibbous phases.
What helped provide evidence that the planets orbit around the sun rather than the earth?
We sometimes see gibbous (nearly but not quite full) Venus. In the Ptolemaic system, we should never see more than a crescent in Venus. Because we do in fact see more, the Ptolemaic model must be wrong. The full range of phases that we see for Venus is consistent only with the idea that Venus orbits the Sun. Galileo was the first to observe the phases of Venus - and hence to find this evidence in support of the Sun-centered system - because he was the first to observe Venus through a telescope. Without a telescope, we cannot tell that Venus goes through phases.

Does Mars go through phases similar to the moon?
Only partly. We never see Mars in a crescent or new phase, just the full and gibbous phases. That's because Mars is farther away from the Sun than the Earth is, so we never see it "inside" our orbit. On the other hand, we see the crescent and gibbous phases of the planet Venus, but never the full or new phases, because when Venus would be "new", it's too close to the Sun to be observed - and when Venus would be "full", it's on the other side of the Sun, and not visible!
Can you see other planets phases?
The easiest phases to see are those of Venus when it comes close to Earth as it overtakes us in its orbit. At that time it is very bright and the crescent phase can be seen in a small telescope.

Does anything else go through phases besides the moon?
Yes. Mercury and Venus have phases. We can't really observe phases for the outer planets, because we always see the bright side, since we are on the same side as the Sun. Any asteroid that gets near enough could also have phases.
