Of course neither the Earth nor the moon was habitable in that era, so there were no native lifeforms to enjoy the views. So billions of years ago, the distance between the Earth and the Moon was just a small fraction of the present distance, and the Moon appeared many times larger in the sky of Earth than it does today, and the Earth appeared four times larger in the sky of the Moon than the Moon appeared in the sky of Earth. It may be noted that tidal interactions cause the Moon to very, very, very slowly increase its distance from Earth. So in a story set on a moon base on the near side of the Moon the Earth will appear about four times as large in the sky as the Moon appears in the sky of Earth.Īnd someone could write a story where the Moon has been terraformed to be habitable and have a breathable atmosphere - kept from escaping by a forcefield or something - and people could walk around outside without spacesuits and enjoy the view of Earth. Since the Earth has about four times the physical diameter of the Moon, obviously the Earth appears to have about four times the angular diameter as seen from The Moon as the Moon appears to have as seen from the Earth. Obviously at any one moment the Earth will be as far from the Moon as the Moon is from the Earth. Obviously the planet Earth has a companion object, the Moon, which looks like the Moon in the sky. Otherwise, you're almost certainly out of luck. If the situation you're describing is artificial, you might be able to get away with it. one or more of the suns have to be a long way away (though again, it might be a small but non-point-like blob rather than merely a really bright star). It probably isn't even possible to get a Tatooine-style double sunrise. WillK's link above shows a second moon being visible as a small but non-point-like object you can probably manage this effect for a single moon, but you won't get anything that looks as big as the parent planet. Earth's fellow planets, even the largest ones, are just points of light without the aid of decent telescopes. You can get a great view of jupiter or saturn from their moons, but most or all of the other moons in those systems look like little points of light. Have a read up on Hill spheres for more information on this subject. To grossly oversimplify, moons and planets that aren't either very small, or very widely separated, tend to have sufficiently strong gravitational interactions with each other that their orbits are changed, usually with one or more parties being flung out of orbit. Save resulting image by pressing Save button.Can you see one large planet? Sure, if your viewpoint is from a moon.Ĭan you see two large planets? Well, probably not. Use Reset button to reset settings to defaults. Use Zoom and Rotate sliders to adjust size and rotation angle of a resulting image, and Twist slider to give it some spin. Resulting image will look more seamless if the right and left edges of your photos match, but if they don't, you can try to improve matters with Mirror switch. With Tunnel switch you can bend your photo around in a concave way, for the opposite effect. After choosing original photo, a default planet image will be generated. Landscape photos are preferable and panoramic shots are even better. Press Open button to select photo from image library on your phone or take a new one. In only a few seconds you can convert any photo into a tiny planet masterpiece and experiment with different levels just by adjusting sliders. TinyPlanet lets you to transform your landscape or panoramic photo into a sphere so that it looks like a tiny planet.
