Since its discovery in 1781, Uranus has been an object of mystery. It lies 2,900 million kilometers (1,800 million miles) from our Sun. This great distance of the seventh planet, along with its long seasons (about 21 years each), are two reasons why Uranus has been slow to reveal its secrets. Thanks to dedicated scientists and engineers, along with the availability of modern equipment, the growth of our knowledge of Uranus has accelerated since the mid-1980 s. Figure 1.1 shows a series of images of Uranus and its rings made by operators of the modern Keck telescope equipped with advanced imaging technology. Table 1.1 lists a few characteristics of this planet.
