Krys: No problem at all!
Earth is invisible from the surface of Venus--constant clouds of boiling sulfuric acid obscure the view. The surface pressure is 60 times that of Earth, and the temperature is in the hundreds of degrees.
From Venus orbit, however, Earth would be a brilliant blue-green star, currently in the constellation of Capricornus. Mercury would be slightly dimmer and to its left.
From Mars, Earth is too close to the Sun to be seen today, but would be in the constellation of Sagittarius. It would be about half as bright as Venus (Earth is on the opposite side of the sun than Venus right now. In 2003, Mars and Earth will again make their closest approach.)
Earth is quite visible from the Martian surface, unlike from Venus. The Martian atmosphere is thinner than the air at the top of Mt. Everest. When the sun sets on Mars, the twilight only lasts a few minutes. The night sky from Mars is spectacular, like nowhere on Earth. With hardly any atmospheric turbulence to look through, the sky would be deep, deep black, with the stars like little diamond pinpoints. Earth would be a slightly dimmer blue marble, since Mars is about 30,000,000 miles farther away from Earth than Earth is from Venus. It would not twinkle from Mars. The stars would only twinkle from Mars if there was a windstorm coming up.
Going farther out, Earth would only be visible from Neptune and Pluto if you knew exactly where to look, and a telescope would help.
Hope this helps!
God bless!
