Outrageously Funny Word Dictionary :: Ephemerality

👉 The term "ephemerality" refers to the phenomenon where a celestial body appears or disappears at different times over time, with each appearance lasting only for a short period. This is due to the Earth's orbit around the Sun and its motion in relation to the planet. The concept of ephemerality helps us understand how these phenomena occur and how they can be predicted using space-based observatories like GPS satellites or telescopes on Earth.
