What are three ways orchids attract insects to spread their flowers’ pollen?

Not sure about the answers but maybe the scent of the flower the colour of the petals and the nectar produced

They depend on birds, bees or insects to spread their pollen to another orchid flower. Such plants produce a smell that attracts pollinators not normally attracted to them. Other orchids trick male flies by making themselves look like female flies.

The object would have to be spherical, orbit the sun, and be traveling in a path with other objects.
