thus giving the Solar System a diameter of 287.46 billion km. Now, that is a lot of zeros, so let’s simplify it into astronomical units. 1 AU(distance from the Earth to the Sun) equals 149,597,870.691
An interferometric study of the Fomalhaut inner debris disk. III. Detailed models of the exozodiacal disk and its origin Context. Debris disks are thought to be extrasolar analogs to the solar system planetesimal belts. The star Fomalhaut harbors a cold debris belt at 140AU c... B Mennesson...

Thus, while a discharge is occurring between the cloud and the Earth a discharge from some other region of the cloud system can occur, abruptly stopping the flow of current to Earth. Such a process is very similar to the process in a “trigatron” type of gap (Lucas, 2001) used to ...

Brightest Star in the Solar System Basic astronomical data Having anorbital periodof 164.79 years, Neptune has circled theSunonly once since its discovery in September 1846. Consequently, astronomers expect to be making refinements in calculating its orbital size and shape well into the 21st century...
