Question:-
How many moons do we have?.
The answer is NOT "One"
If you count meter sized asteroids caught up inside the gravitational fields of both Earth and the one moon you can see, we may have many many many more.

Interesting discussion of what constitutes a "moon." According to this article, strictly from an astronomical standpoint, SD could be correct. www.universetoday.com/60072/what-is-a-moon/ |

Cassini skims Saturn's atmosphere www.bbc.co.uk/news/science-environment-40902774The Cassini probe has begun the final phase of its mission to Saturn. The satellite has executed the first of five ultra-close passes of the giant world, dipping down far enough to brush through the top of the atmosphere. It promises unprecedented data on the chemical composition of Saturn. It also sets the stage for the probe's dramatic end-manoeuvre next month when it will plunge to destruction in the planet's atmosphere. More here... www.nasa.gov/mission_pages/cassini/main/index.htmlAs NASA's Cassini spacecraft makes its unprecedented series of weekly dives between Saturn and its rings, scientists are finding -- so far -- that the planet's magnetic field has no discernible tilt. This surprising observation, which means the true length of Saturn's day is still unknown, is just one of several early insights from the final phase of Cassini's mission, known as the Grand Finale. Other recent science highlights include promising hints about the structure and composition of the icy rings, along with high-resolution images of the rings and Saturn's atmosphere. |

Commemorating the 40 year anniversary of the launch of Voyager 1 and 2, NASA has put up three posters that are free to download at this website: voyager.jpl.nasa.gov/downloads/I've downloaded the first of the three and - once I've found a new place to live - I'll have it printed, framed and hung on my living room wall  |

The Universe does not give a flying crap about our classifications of objects within it and it keeps proving we think too small. For instance, astronomers have discovered a binary asteroid/comet hybrid that's cruising around in the inner part of the Solar System and they can't really figure out why and how this thing is where it is and what the heck to call it. Astronomers Have Spotted a Strange Hybrid Asteroid in Our Solar System Yes, you read that right. It's a comet, but it's in the main asteroid belt, technically making it an asteroid and then, to make it all a little weirder, it's actually in two pieces that orbit each other. Just when we thought we knew, the Universe throws another curve ball. Well, two actually |

If any of his plans for manned space travel succeed, Elon Musk will quite possibly be remembered for the rest of human history as the most influential person of the 21st century. Even if it doesn't work, he's certainly raising the bar for the term "visionary" and it's a bar that has needed to be raised for decades. I for one am cheering him on |

Musk is inspiring more people than you think. My daughter was just telling me that the organization where she works asked her to write a five year business plan. She said she had just finished her plan when she looked at her computer and saw a story with the headlines titled, "Elon Musk has a five year plan to colonize Mars." She said after she read that, she called up her 5 year plan, hit delete and started over.
