An orbit is the curved path followed by an object around a point in space, such as a planet around the sun or a moon around a planet. Objects in orbit are held in place by the force of gravity.
Types of Orbits
There are different types of orbits, including:
Circular Orbit: An orbit in the shape of a circle, with the object moving at a constant distance from the center.
Elliptical Orbit: An orbit in the shape of an ellipse, with the object moving at varying distances from the center.
Polar Orbit: An orbit that passes close to the north and south poles of the central body.
Geostationary Orbit: An orbit in which a satellite remains above the same point on the Earth's surface at all times.
Factors Affecting Orbits
Several factors can affect the orbit of an object, including:
Mass of the Central Body: A more massive central body will exert a stronger gravitational force, affecting the shape and size of the orbit.
Velocity of the Object: The speed at which the object moves will determine the shape and stability of its orbit.
Altitude of the Orbit: The distance of the object from the central body can affect the stability and duration of the orbit.

Observe seasonal patterns of sunrise and sunset to describe the relationship between the number of hours of daylight and the time of year (e.g., more hours of daylight during summer as compared to winter).
