Are there planets in the Zeta Reticuli binary star system?

Answer 1

Not that we know of.

This is an interesting question: the Kuiper belt, which contains numerous comets, large asteroids, dwarf planets (like Pluto), and possibly the ninth planet (ten times the size of Earth) is similar to the debris disc of the Zeta Reticuli system.

We can't be positive about the Zeta Reticuli system either, since we can't be positive that the debris disc around it contains a planet, even though we can't be positive that there is one in our own Kuiper belt.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
