226 views

If light travels in straight line and isn’t obstructed till it hits something then why are the front stars easily visible but the the last ones aren’t like does sunlight doesn’t reach those little shits? I can’t see youranus neither Neptune and other ones but after a while planets are visible yet again? Like are they out of the solar system and someone else glows then or what?

Uranus has HALF the diameter of Saturn thus 1/4 of the cross-section. All else being equal, Uranus would reflect 25% of the light.

Uranus is DOUBLE the distance to Earth compared to Saturn, thus it appears as half the diameter when viewed from Earth. All else being equal, Uranus would reflect 25% of the light.

Uranus is blue/green, while Saturn is yellow/brown. All else being equal, Uranus would reflect about 80% of the light.

Combining just these 3 factors Uranus reflects only 5% of the light that Saturn does.
