Yes. One of the physical laws that describe orbits in response to a central force is the fact that the smaller the orbit, the faster the orbiting body travels. Earth's average speed in its orbit around the sun is 18.5 miles (29.8 km) per second. Mercury's average speed in its orbit around the sun is 29.7 miles (47.9 km) per second.
So, Mercury may be the closest planet to the Sun, but it can also be one of the coldest. Even when you are on the side of Mercury that is receiving heat and light directly from the sun, temperatures on Venus are even hotter.n the picture above, taken from a satellite orbiting Earth, you can see little Mercury in front of the gigantic Sun. This small planet is so close to the Sun that it only takes it 88 days to orbit the star, compared with Earth's 365 days and Pluto's 248 years.
