How to Find Pluto in the Night Sky: July 8

Pluto and New Horizons, July 8, 2015

On July 14, a NASA spacecraft will make a close flyby of Pluto, sending back the first up-close images of the dwarf planet's surface.

In anticipation of the New Horizons flyby, this sky chart can help you find Pluto in the night sky (with the assistance of a high-power telescope).

The chart shows the positions of Pluto and New Horizons as seen through a high-power telescope eyepiece with a field of view of 15 arc minutes. Both are moving from left to right. The leftmost dots (labeled "Pluto" and "New Horizons") show their positions at 1 a.m. EDT (0500 GMT) on Thursday (July 9), and the remaining dots show their positions at the same time through the morning of July 16.

Notice that the paths cross between the positions for July 14 and July 15, the exact time that New Horizons flies by Pluto. Of course, New Horizons is too small and far away to be visible even in the largest telescopes, but it's interesting to see its position relative to Pluto.

New Horizons is the first probe to study Pluto up close, and no telescopes currently in operation can resolve the dim, distant dwarf planet well enough to get a good look at its surface features and composition.

New Horizons' most recent images of Pluto and its five moons are already beginning to reveal never-before-seen details of this strange system.

After New Horizons passes by Pluto, it will travel deeper into the Kuiper Belt, a region of icy bodies beyond Neptune, where it may study study another object (if NASA approves a proposed mission extension). Only four other space probes have ever traveled into that distant region.

Starry Night Sky Columnist

Geoff Gaherty was's Night Sky columnist and in partnership with Starry Night software and a dedicated amateur astronomer who sought to share the wonders of the night sky with the world. Based in Canada, Geoff studied mathematics and physics at McGill University and earned a Ph.D. in anthropology from the University of Toronto, all while pursuing a passion for the night sky and serving as an astronomy communicator. He credited a partial solar eclipse observed in 1946 (at age 5) and his 1957 sighting of the Comet Arend-Roland as a teenager for sparking his interest in amateur astronomy. In 2008, Geoff won the Chant Medal from the Royal Astronomical Society of Canada, an award given to a Canadian amateur astronomer in recognition of their lifetime achievements. Sadly, Geoff passed away July 7, 2016 due to complications from a kidney transplant, but his legacy continues at Starry Night.
