Moons of our Solar System
- moons are the natural satellites of planets – most are small rock globes that continually orbit the planet – held in place by the planet’s gravity.
- as of October 2008, more than 176+ known natural moons in our Solar System.
- every planet in our Solar System has a moon or some moons, apart from Mercury and Venus.
- very few of the moons have atmospheres – including Saturn’s moon Titan, Jupiter’s Io and Neptune’s Triton.
- Jupiter’s moon – Ganymede, largest moon in the Solar System.
- second largest is Saturn’s moon – Titan; icy-cold, and is only moon with thick atmosphere of nitrogen gas. (wikipedia – Titan)
