In the Old West, they used to say, "There's GOLD in them thar hills!" In the future, prospectors might just be saying that about asteroids in space! Asteroids, sometimes called minor planets, are rocky, airless remnants left over from the early formation of our solar system about 4.6 billion years ago. They may contai useful or even precious minerals and metals. The current known asteroid count is at least 1,351,400. Most of this ancient space rubble can be found orbiting the Sun between Mars and Jupiter within the main asteroid belt. Asteroids range in size from Vesta – the largest at about 329 miles (530 kilometers) in diameter – to bodies that are less than 33 feet (10 meters) across. The total mass of all the asteroids combined is less than that of Earth's Moon. Celebrating the vintage art and designs of space travel from the early and mid-20th century, Anderson Design Group poster artists created this original illustration and vintage poster art of what the classic Old West miner might look like in the Space Age. A cheeky addition to your home or office decor, this hand-rendered design will look out-of-this-world as an art print, poster, notecard, postcard, metal sign, canvas, or mini canvas.
