Do you want to know the date of the full moon? The full moon’s name? The moon’s current phase? The moon’s rising and setting time? How about when the moon is at perigee – closest to Earth for the month? Or maybe how long the lunar month lasts this time around? Find all this and more on our moon facts page. If you can’t find what you’re seeking, contact us and we’ll try to help you!

Great site!!…I have an astronomy question:
Suppose we have a “perfect” spacecraft with the following properties:
1: infinite fuel with negligible mass
2: infinite power (or at least enough to take the following journey:
The journey is halfway to Mars, with acceleration = G(9.80665 m/s2), as on Earth, and then braking to -G (after turning around). What is the shortest time this journey could take?…perhaps what you really want to do, though, is to gradually reduce this so that when you get to Mars, you’re at Mars acceleration, and on the way back, increase the acceleration to Earths, so that passengers would experience the most gradual gravitational change. How much fuel would it take, using the best existing rocket fuel, and say, 10 Tons of spaceship mass?…is this totally outrageous?
Sorry, Alex, but this question is beyond my capability to answer. I know that spacecraft sent out to planets follow a curved elliptical orbit around the sun, so as to minimize on fuel consumption. Check out the diagram at http://www.astrosociety.org/education/publications/tnl/34/space3.html.
19 march 2011 the moon is the closest to earth.I want to know which countries will be the closest to the moon..
Serpil,
Sorry for my late response but I didn’t see your inquiry until now. When the moon came closest to Earth on 2011 March 19, it was at zenith (straight overhead) over the Indian Ocean, at roughly 75 degrees east longitude and 4 degrees south latitude. That’s south of India and fairly close to the Addu Atoll.
