Venus is closer to the sun than any other planet except Mercury. Venus’s distance from the sun is about 67.2 million miles, compared with about 93 million miles from the Earth. Venus orbits the sun in a circular motion. The Earth and all other planets orbit the sun in an oval shaped motion. Venus takes about 225 Earth days to go around the sun once compared to earth’s 365 days. Unlike Earth, Venus does not rotate in the same direction in which it travels around the sun. Rather, Venus rotates in the opposite direction and spins around once every 243 Earth days.

Venus can be see going through changes in shape and size. These changes are called phases much like the moons. Earth does not go through phases such as those of Venus.

One reason Venus is some much hotter than Earth is due to a runaway greenhouse effect. But this is not the only reason Venus is so much hotter. Earth and Venus have the same total amount of carbon dioxide. The difference is in the way the two planets use the gas. Plants on Earth use carbon dioxide to do photosynthesis, which releases a waste gas called oxygen in return. Plant life on Earth draws a massive amount of carbon dioxide out of the air. Because Venus is so extremely hot it has no proof of plant life at all; therefore Venus does not have the advantage of photosynthesis help to reduce the carbon dioxide level.

th and Venus do have some similarities when it comes to the their surfaces features. Both planets have mountains, valleys, and canyons. Venus’s surface is still very different from Earth’s surface. For example, Venus has crowns, ring like structures that range from 95 to 360 miles in diameter. These crowns form when hot material inside the planet rises to the su
