With its enormous size and mass, you'd think Jupiter would rotate slowly around its axis. With a rotational velocity of 45,300 km/h, it is the fastest spinning planet in the solar system. As a result, a day on Jupiter lasts only 9 hours and 55 minutes. A year, on the other hand, is much longer; Jupiter orbits the sun once every 11.8 Earth years.

Few odours are as appealing as "new car smell," and it's not just because it's nice to be in a brand new car. However, while the scent may be strangely satisfying, it is actually a combination of 50+ chemicals (known as "volatile organic compounds") that are released into the car and decay quickly over time. The concentrations found in a typical new car are not dangerous, but VOCs found in nail polish, auto fuel, and petroleum contribute significantly to the new car smell.

The first hot air balloon was launched in 1783, transporting a sheep, duck, and rooster. In France, the Montgolfier brothers created the hot air balloon. They began experimenting with balloons after witnessing the heat of a fire raise their drying clothing. Because it was uncertain how flying at such altitudes might impact humans, the initial flight included animal passengers. The flight was a perfect success, and the animals arrived safely and largely unscathed. The sheep, however, managed to land on the rooster.
