Hoping to See Asteroid 2005 YU55? There’s an App for That!

Starmap is an astronomy/planetarium app for the iPhone and iPad. A companion app, called Spacemap is an extended orrery that lets you view the phases, motions, and positions of items in the Universe all from your iPad. If you’re hoping to track down Asteroid 2005 YU55 as it comes close to Earth on Nov. 8, you might want to check out both Starmap and Starmap. You can see this asteroid in both apps, but Spacemap is the only application available in the iTunes store that displays 2005 YU55’s orbit in 3D animation.

UPDATE: The contest is now closed and the winners have been notified.

Want to win a copy of either Starmap or Spacemap? Universe Today has a two copies of each to give away to the first four readers to answer this question correctly: What year was the last time an asteroid as big as 2005 YU55 passed by Earth?

Answer in the comment section, and indicate which app you’d like. We have two of each to give away. First four commenters to answer correctly wins. Make sure your contact info on Disqus is correct, as that is you’ll be contacted.

If you’re not a winner, you might want to check out Starmap and Spacemap, as they are now 50% off, for a limited time. Starmap Pro 2.3.2 in iTunes, and Spacemap 1.1 in iTunes.

Starmap creator Frederic Descamps is a professional astronomer.
