4. New discovery may redefine solar system's outer frontier This is an orbit diagram for the outer solar system. The Sun and Terrestrial planets are at the center. The orbits of the four giant planets, Jupiter, Saturn, Uranus and Neptune, are shown by purple solid circles. The Kuiper Belt, including Pluto, is shown by the dotted light blue region just beyond the giant planets. Sedna's orbit is shown in orange while 2012 VP113's orbit is shown in red. Both objects are currently near their closest approach to the Sun (perihelion). They would be too faint to detect when in the outer parts of their orbits. Notice that both orbits have similar perihelion locations on the sky and both are far away from the giant planet and Kuiper Belt regions.

5. The Night Sky Sky & Telescope Friday, March 28  The huge, bright Winter Hexagon nearly fills the southwestern sky at dusk. Start with bright Sirius in the south, marking the Hexagon's lower left corner. High above Sirius is Procyon. From there look even higher to Pollux and Castor with bright Jupiter below them, then from Castor farther lower right to Menkalinen and Capella, then lower left to Aldebaran, then duck around lower left to Rigel at the bottom of Orion, and back to Sirius. Within the Hexagon shine Jupiter and Betelgeuse. Saturday, March 29  You can tell winter is gone for good, astronomically speaking: As soon as the stars come out, the Big Dipper is already higher in the northeast than Cassiopeia is in the northwest. Sunday, March 30  This is the time of year when the dim Little Dipper juts to the right from Polaris (its handle-end) during evening hours. The much brighter Big Dipper curls over high above it, "dumping water" into it.  New Moon (exact at 2:45 p.m. Eastern Daylight Time). Monday, March 31  It's getting to be Virgo Galaxy Cluster time, as Virgo climbs up in the southeast through the evening. North of Gamma Virginis (Porrima), explore the area around the giant galaxy M49 with your telescope using Sue French's Deep- Sky Wonders article in the April Sky & Telescope, page 56. Tuesday, April 1  The biggest and brightest asteroids, 1 Ceres and 4 Vesta respectively, are only about 2° apart in eastern Virgo, some 12° northeast of Mars. They've brightened to magnitudes 7.1 and 5.9, respectively. They'll be at opposition in mid-April.
