Subject: [WSFA] Neptune's first orbit: a turning point in astronomy
Reply-To: WSFA members <WSFAlist at KeithLynch.net>

Excerpt:
Astronomers will celebrate a remarkable event on 11 July. It will be
exactly one year since the planet Neptune was discovered. Readers should =

note a caveat, however. That year is a Neptunian one. The great icy
world was first pinpointed 164.79 years ago =96 on 23 September 1846. And=

as Neptune takes 164.79 Earthly years to circle the sun, it is only now
completing its first full orbit since its detection by humans. Hence
those anniversary celebrations.
