Did Venus have a secret companion hiding in plain sight for years? If not, what were they really seeing? The true story of this mysterious moon, "Neith", may surprise you. Come along as we learn about how the scientific method was used to find the truth, and how the lesson from the story of Venus's moon is applied in modern astronomy through the search for Earth's L4 trojans.
