Question

why is uranus virtually invisible to the naked eye?
it is very far away from earth.
it is obscured by a constant haze.
its halo bends light around it.
it does not reflect light

Explanation:

Uranus is far from Earth (about 2.6 billion km on average), so the sunlight it reflects spreads out, making its apparent brightness too low for the naked eye to detect. The other options are incorrect: it has no constant obscuring haze, no halo bending light, and it does reflect sunlight (all planets reflect sunlight).

Answer:

It is very far away from Earth
