The ISS circles the Earth every 90 minutes. It travels at about 17,500 miles (28,000 km) per hour, which gives the crew 16 sunrises and sunsets every day. In the more than 15 years that people have been living onboard, the Station has circumnavigated the Earth tens of thousands of times.
Generally, these beautiful paints are called metallic when they imitate metals like gold, silver, etc., and they are often called Pearlescent or Pearl, when they are other colors like white, blue, red, etc.
The color of the pearl depends very much on the species of mollusk that produced it, and its environment. White is perhaps the best-known and most common color. However, pearls also come in delicate shades of black, cream, gray, blue, yellow, lavender, green, and mauve. Black pearls can be found in the Gulf of Mexico and waters off some islands in the Pacific Ocean.
