Orbitnya Elips Dan Sangat Lonjong

An orbit is the path followed by a celestial object, such as a planet or a moon, around another object, such as a star. There are several different types of orbits, including circular, elliptical, and highly elliptical.

An elliptical orbit is one in which the object follows an oval-shaped path around another object. The shape of the ellipse is determined by two points, known as the foci, that are located inside the ellipse. The closer the foci are to each other, the more elongated the ellipse becomes. An elliptical orbit can be nearly circular or highly elongated, depending on the distance between the foci.

A highly elongated elliptical orbit, also known as a very eccentric orbit, is one in which the object follows a path that is very elongated or stretched out. This type of orbit can be very unstable, and the object can experience large variations in speed and distance from the central object. Objects in highly eccentric orbits can also have very long orbital periods, taking many years or even centuries to complete one orbit.

One example of an object with a highly elongated elliptical orbit is Halley’s Comet. This famous comet has an orbital period of about 76 years and follows an orbit that is very elongated. At its closest approach to the sun, known as perihelion, the comet is about 0.6 astronomical units (AU) away from the sun. At its farthest point, known as aphelion, it is about 35 AU away.

Another example of an object with a highly eccentric orbit is the dwarf planet Pluto. Pluto’s orbit is very elongated, with an eccentricity of 0.25. This means that at its closest approach to the sun, it is about 30 AU away, while at its farthest point, it is about 50 AU away.

In conclusion, an elliptical orbit is one in which an object follows an oval-shaped path around another object. The shape of the ellipse is determined by two points, known as the foci. A highly elongated elliptical orbit is one in which the object follows a path that is very stretched out or elongated. Objects in highly eccentric orbits can experience large variations in speed and distance from the central object and can have very long orbital periods. Examples of objects with highly elongated elliptical orbits include Halley’s Comet and the dwarf planet Pluto.
