Here are the top ten articles for the Astronomy Site! These rankings are live and get reset at the beginning of each month, so check back often to see what your fellow visitors are most interested in!

1. Visiting Venus – Facts for Kids
Would you like to visit another planet? How about Mars or Venus? Apollo astronaut Buzz Aldrin wants to see astronauts on Mars, but could Venus be a better choice?

2. Cassini-Huygens – the Prime Mission
Saturn: magnificent rings, a planet-sized moon, and dozens of smaller moons. Three spacecraft had flown by before Cassini-Huygens was launched in 1997. But this mission wouldn't just fly by and snap some photos. It was going to get up close and personal.

3. Mars Facts for Kids
Mars has no little green men, but it's a fascinating place. It has a mountain three times the height of Everest and a deep valley that dwarfs the Grand Canyon. Although Mars has no liquid water on the surface, if the southern polar icecap melted, it could cover the planet 36 feet deep in water.

4. Jean-Dominique Cassini
The Cassini Mission to Saturn is one of NASA's best known undertakings. For nearly thirteen years it's sent images and data back from the ringed planet and its moons. But who was the Cassini who gave his name to the spacecraft?

5. ABC of Astronomy – C Is for Cosmic Rays
Hundreds of cosmic rays zip through your body every minute. They're a danger to astronauts, and may damage the electronics of satellites and spacecraft. Some aren't cosmic, none are rays, and a few seem to be impossible. What are they and where do they come from?

6. Venus Facts for Kids
It's the planet most likely to mistaken for a UFO. It spins backwards on its axis. A day is longer than a year. It's Venus! Some call it Earth's twin, but I think you'll see that we don't have all that much in common.

7. Rosetta the Comet Chaser
Rosetta, the European Space Agency (ESA) spacecraft, traveled for ten years and billions of miles in order to rendezvous with a comet, accompany it as it moved through the inner Solar System past the Sun, and deploy a lander.

8. Halley's Comet
Every 75 years or so a very special member of the Solar System swoops close to the Sun, becoming visible in our skies like a cosmic ghost. Read about Halley’s Comet, the most famous comet of all.

9. Sputnik – The Space Race Begins
On October 4, 1957 a small object had people around the globe looking excitedly – or anxiously – up at the sky. It's so common now that people today could scarcely imagine the effect that the first artificial satellite had. Sputnik began the Cold War's space race.

10. Chamaeleon – the Southern Stellar Lizard
Chamaeleons lived in lands exotic to 16th-century Europeans. Yet although color-changing lizards are fascinating, Chamaeleon the constellation is a small, dim southern sky constellation with no associated mythology. Why does it even exist? Is there anything of interest there?
