An asteroid itself does not emit light, like a comet. It can only reflect light like the moon. The moon only looks bright because it reflects light from the sun. So when you think about it, an asteroid, like the one that passed the earth back in NOV 2011, was only the size of an aircraft carrier which is negligible compared to the moon. The moon doesn't seem bright compared to the sun, and so an asteroid wouldn't seem bright compared to the moon. You can't actually see an asteroid with the naked eye; it would take a telescope.
The Sun would be a mere speck of light from Pluto.
Pluto is about 40 AU from the Sun so using the inverse square law it will be about 1,500 times dimmer than from Earth
Because of its distance from the Sun, it has dim sunlight.
Uranus has an apparent magnitude of 5.9 to 5.32.
Pluto is light brown in color, having a highly reflective, icy surface.
...would be dim.
The word opposite to the word dim is bright.
An extremely bright star (essentially a point source).
it has bright
Bright and dim are antonyms. Bright means having a high level of light or shining with intensity, while dim means having a low level of light or lacking brightness.
If you're talking about a gender difference, then the opposite is a bright girl. Otherwise the opposite of 'bright boy' is 'dull boy'
