"The Early Bird not only Gets the Worm, but also 4 Pre-Dawn Planets Lined Up in a Row"

Scheduled air date: 2002 Oct 07-13

For the next couple of weeks, the planets Mercury, Mars, Jupiter and Saturn can all be seen in the pre-dawn sky...
(Shown about 60 minutes before sunrise for mid-Northern latitudes.)

...the planets appear in a line because, like all planets in our Solar System except most-distant Pluto, their orbits are in approximately the same plane.
(Solar System view from beyond Pluto's orbit showing the planets in their current relative positions.)
