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?

Things that are further away need to be larger in order to see them. Saturn and Jupiter are both easily visible because of how huge they are. Uranus and Neptune are both significantly smaller than Jupiter and Saturn, and further away, so they reflect less sunlight back at Earth.
Uranus actually is visible with the naked eye, but only in areas of the world where there isn’t much light pollution.
You can’t see Neptune and Uranus with the naked eye because they are far away. Uranus is nearly twice as far from the Sun as Saturn, and Neptune is 3 times farther than Saturn. You can see them with a telescope though.
> after a while planets are visible yet again?
No, there are no visible planets past Neptune. If you’re talking about planets outside the solar system (exoplanets), then they aren’t really visible – we can just detect them by seeing their effect on the stars that they orbit.
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.
