Which orbit the orbit of mars or the orbit of venus is closer to the earths orbit and how do you know?

Venus's orbit is the closest. I know because I have looked up the distances of both of them in a book. But how is that fact known? it goes back to Johannes Kepler in the early 1600s who formulated the laws of planetary motion.
Kepler probably noticed that the outer planets Jupiter and Saturn showed the least retrograde motion and he deduced that they therefore must have the largest orbits. Kepler scaled the orbits in terms of their time periods.
The absolute distance to Venus was later found by triangulation, measuring the position of Venus relative to the Sun from two different points on Earth during a transit of Venus. Because the size of the Earth was known, this method yielded the size of Venus's orbit, and then all the other orbits by Kepler's 3rd law. Probably the size of Mars's orbit was also measured by triangulation at some stage as a check.

Why is Venus hotter then earth?
Two reasons I know of; Venus is closer to the Sun than the Earth is. Venus has a very thick CO2 atmosphere that captures much of the solar heat.
What is the revolution of the planet Venus?
if anyone question that question .can please answer the , cause i don`t know the answer
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.

Why did Copernicus realized that Venus is an inferior planet?
Is it because Venus never goes through retrograde motion, Venus is made of cheap, low quality material, Venus never reaches opposition or is it because Venus never gets as bright as Jupiter? Please choose one of the following.
What is unusual about Venus orbit?
what is unusual abut venus orbit is goldylocks and you have t6o loook out a teleshope to know what this is
What two planets are closer to earth?
Venus and Mars. You should know this.

What can you say about the orbit time of a satellite in lower orbit then geostationary one?
Its closer to the earth. Can say much more without know the velocity of the satellites
How they stay in orbit in space without crashing back to earth or flying off into space?
they are able to stay in orbit because of the earths gravitaional pull which keeps the shuttle in orbit so that it will not crash there is a theory that if the earths gravity changed the slightest bit everything we know would change
Earths moon?
If you want to know the order it's not sun, moon, earth It's Mercury, Venus and then earth.
Is the earths orbit faster than the speed of light?
We know that the answwer must be "No", simply because we know that NOTHING is faster than the speed of light.
How many satellites orbit the planet Venus?
Venus has no natural satellites. The Soviet Union launched four Venera orbiting probes in the mid-1980s which may still be in orbit, although they stopped transmitting years ago. I believe that the US also has a probe remaining in Venus orbit.
Which planet is easiest to see from earth?
Venus can be the brightest planet. Jupiter is the next brightest and can be seen in the middle of the night when the sky is darkest. Venus (whos orbit is closer to the Sun than the Earth orbit) can never be seen at midnight.

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.
