Definition
  1. Noun:
    • (Astronomy) The angle between the orbital plane of a celestial body and the plane of the ecliptic, measured in degrees. This is a specific astronomical parameter that describes the tilt of an object's orbit around the Sun relative to Earth's orbital plane.
Usage
  • As a subject: The inclination of an orbit is a fundamental orbital element.
  • In measurement: Astronomers calculated the inclination of the orbit to be 7 degrees.
  • With possessives: The comet's inclination of orbit is very high.
Examples
  • Pluto has a high inclination of its orbit compared to the planets.
  • Determining the inclination of an orbit helps classify if an object is a planet or a trans-Neptunian object.
  • A low inclination of orbit, like that of Venus, means it orbits close to the plane of the solar system.
Advanced Usage
  • In celestial mechanics, a zero-degree inclination of an orbit means the object orbits in exactly the same plane as Earth's orbit (the ecliptic).
  • The term is often used in the context of describing and differentiating between planets, asteroids, and comets based on their orbital characteristics.
Variants and Related Words
  • Orbital inclination (n): This is a more common and synonymous phrasing for "inclination of an orbit."
    • The orbital inclination of Mercury is 7 degrees.
  • Inclination (n): In a general or broader astronomical context, "inclination" can refer to the angle between two planes or axes.
  • Ecliptic (n): The plane of Earth's orbit around the Sun, which serves as the primary reference plane for measuring orbital inclination in the solar system.
Synonyms
  • Orbital tilt: A less technical term describing the same concept.
  • Axial tilt is not a synonym. Axial tilt refers to the angle of a planet's rotational axis relative to its orbital plane, which is a different property.
Related Terms and Context
  • Orbital plane (n): The flat, imaginary surface that contains an object's orbit.
  • Orbital element (n): One of the parameters required to uniquely identify a specific orbit. Inclination of an orbit is one of these key elements.
Noun
  1. (astronomy) the angle between the plane of the orbit and the plane of the ecliptic stated in degrees
