Our friends at behäppi from Estonia have expanded their series of challenging wooden puzzles with these wonderful new planet puzzles .

So if you are fascinated by the galaxy, the solar system or the planets, then this is definitely something for you!

With a radius of 1,500 miles (2,440 kilometers) , Mercury is the smallest planet in our solar system and the closest to the sun. It is just over 1/3 as wide as Earth. At an average distance of 36 million miles (58 million kilometers), it takes sunlight 3.2 minutes to travel from the sun to Mercury. Mercury is the fastest planet in our solar system, traveling through space at nearly 30 miles (47 kilometers) per second. Because Mercury is the fastest planet and has the shortest distance to travel around the sun, it has the shortest year of any planet in our solar system - 88 days. Because of Mercury's elliptical - egg-shaped - orbit and its slow rotation, the sun appears to briefly rise, set, and rise again at some spots on the planet's surface. The same thing happens in reverse at sunset. Mercury's surface temperatures are both extremely hot and cold. Because the planet is so close to the sun, daytime temperatures can reach highs of 796 °F (430 °C). Without an atmosphere to retain this heat at night, temperatures can drop to as low as -180 °C.

This 49-piece 20cm puzzle shows Mercury in stunning clarity. The image, provided by NASA, is one of the clearest images of Mercury ever.

The difficulty level of this puzzle is high. Although the puzzle is challenging, the clear and high-quality illustration makes putting this Mercury puzzle together a lot of fun.
