A great image of our Earth from Saturn.

More pictures are from http://www.nasa.gov/mission_pages/cassini/main/index.html

To imagine: the Earth looks at most 2" large (mv=+3) and the Moon 0.5" (mv=+8) max. 48" separated.
So a 20cm telescope is required to see Earth as a (tiny) ball and binos are required to see the Moon and a 75cm scope is required to see the Moon as a ball.
7 billion people living on such a tiny 'star' like object !

There's no place like home! :earth:


... and billions upon billions of planets (or so it seems) in the known universe ...

Nice images. It's amazing to think how we are a tiny spec in the night sky.

thats cool info skysurfer, cheers.
looking at the earth and moon picture makes me see earth/moon as a binary system, rather the earth and the moon.

Here is a similar view from Encaladus looking towards the Sun and inner planets from a Stellarium screen shot. Note Saturn's rings are edge on from here.

iT JUST SHOWS HOW INSIGNIFICANT WE ARE in this big wide universe.

We are not at the centre of the universe as the ancients once believed.

We are just a "Pale blue Dot" with no special privileges.
