41. The belt is thought to extend out at least 50 astronomical units , and perhaps as far as 100. 42. One astronomical unit , the distance between the Earth and the sun, equals about 92 . 7 million miles. 43. In the original pilot episode, g, and has a range of 440 astronomical units when carrying minimal cargo. 44. The binary system consists of two red dwarfs orbiting each other at a distance of 1.9 astronomical units . 45. At the distance of this system, this is equivalent to a linear distance of about 93 Astronomical Units . 46. This distance is 10 parsecs for stars and 1 astronomical unit for planets and small Solar System bodies. 47. Its distance from the Sun is approximately 80 to 100 astronomical units ( AU ) at its closest point. 48. Pholus has not come within one astronomical unit of a planet since 764 BC, and will not until 5290. 49. Around 50 astronomical units distant from Gamma Corvi A, it is estimated to complete an orbit in 158 years. 50. This suggests it may be orbited by a disk of dust at a radius of more than 15 astronomical units
