A Low Earth orbit is described as which shape?

• A. Elliptical
• B. Geostationary
• C. Circular
• D. Hyperbolic

Answer: (C)

Orbits around a planet are conic sections, and a circle is the special case where the satellite stays at a constant distance from the planet. Low Earth orbit is typically described as circular because engineers aim to keep the satellite at roughly the same altitude, giving a stable, predictable path suitable for communications, imaging, and tracking. In practice, many LEOs are near-circular, but the idea most often presented is a circular orbit for simplicity and consistency. The other shapes don’t fit as well in this common description: a hyperbola would mean the satellite isn’t bound to Earth, a true geostationary orbit is a much higher altitude with a specific 24-hour period, and a generic ellipse would imply a varying distance from Earth, which is not the usual portrayal of a typical, stable LEO.
