"Inferior planet" refers to Mercury and Venus, which are closer to the Sun than Earth is. "Superior planet" refers to Mars, Jupiter, Saturn, Uranus, and Neptune (the latter two added later), which are further from the Sun than Earth is. The terms are sometimes used more generally; for example, Earth is an inferior planet relative to Mars.
A planet that orbits a pulsar or a rapidly rotating neutron star. PSR B1257+12 A, B and C: Rogue planet: Also known as an interstellar planet. A planet that is not bound to any star, stellar remnant or brown dwarf. OGLE-2016-BLG-1928: Superior planets: Planets whose orbits lie outside the orbit of Earth.

Knowledge of the location of Earth has been shaped by 400 years of telescopic observations, and has expanded radically since the start of the 20th century. Initially, Earth was believed to be the center of the Universe, which consisted only of those planets visible with the naked eye and an outlying sphere of fixed stars. [1]
The planet, called LHS 3154 b, orbits at about 2.3% of Earth's orbital distance from the sun, circling its star every 3.7 days. It is much closer even than our solar system's innermost planet ...
This is in contrast to the so-called superior planets, such as Mars, which appear to move independently of the Sun. infrared astronomy The subfield of astronomy that studies astronomical objects detectable at infrared wavelengths. International Astronomical Union (IAU) interstellar medium (ISM) The matter that exists in the space between the ...
This distance is not the same as its apastron, because no planet's orbit has its star at its exact centre. [62] The inclination of a planet tells how far above or below an established reference plane its orbit is tilted. In the Solar System, the reference plane is the plane of Earth's orbit, called the ecliptic.
Jupiter is the biggest planet in our solar system, according to NASA. Jupiter’s radius is over 11 times the equatorial radius of the Earth.
The poles of astronomical bodies are determined based on their axis of rotation in relation to the celestial poles of the celestial sphere. Astronomical bodies include stars, planets, dwarf planets and small Solar System bodies such as comets and minor planets (e.g., asteroids), as well as natural satellites and minor-planet moons.
