Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the symbol?i
2. What is the range?0° to 180°
3. Why do some satellites fly straight while others tilt?Satellites that fly straight over your head have an inclination of 0 degrees, staying in the reference plane. Those that tilt cross the reference plane at an angle, so they travel over different parts of the Earth.
4. How does orbital inclination affect where a satellite can see on Earth?The inclination decides how high a satellite can see and which parts of Earth it passes over. A 0‑degree orbit stays over the same spot, while a 90‑degree polar orbit goes over the poles and eventually every spot on Earth.

Keplerian Orbital Elements: A set of six parameters that uniquely define an orbit and its position in space.
Ascending Node: The point where an orbiting body crosses a reference plane moving from south to north.
Transit Method: A technique for detecting exoplanets by observing the periodic dimming of a star as a planet passes in front of it.
