The object Kowal, which is orbiting the sun between Saturn and Uranus, was discovered on November 1, 1977. Object Kowal has an angular motion of only 0.0149 degrees per day, a speed scarcely greater than that of Uranus. The object is extremely faint, having a visual magnitude between 18 and 19. However, Kowal is still much brighter than any known comet would be at that distance. It has, therefore, been concluded that Kowal is an asteroid. It is pointed out that the object Kowal might turn out to be the first of a new belt of asteroids between Saturn and Uranus. The region between Saturn and Uranus could easily contain an earth's mass worth of asteroids which have remained undetected until now. It has been estimated that Kowal has a radius in the region from 80 to 320 km. The object has a semimajor axis of 16.340 AU and a period of 66.1 years.
