(119070) 2001 KP₇₇ (better known as 2001 KP77) is a 4:7 resonant Trans-Neptunian object (TNO) located in the kuiper belt. It was discovered on May 23, 2001, by Buie, M. W. at Cerro Tololo. May 23 is the 143rd day of the year in the Gregorian calendar (144th in leap years). ... This article is about the year 2001. ... Provisional designation of in astronomy is the naming convention applied to astronomical objects immediately following their discovery. ... Minor planets, or planetoids are minor bodies of the Solar system orbiting the Sun (or of other planetary systems orbiting other stars) that are larger than meteoroids (the largest of which might be taken to be around 10 meters or so across) but smaller than major planets (Mercury having a... A trans-Neptunian object (TNO) is any object in the solar system that orbits the sun at a greater distance on average than Neptune. ... In astronomy, an epoch is a moment in time for which celestial coordinates or orbital elements are specified. ... In astrodynamics, under standard assumptions any orbit must be of conic section shape. ... In geometry, the semi-major axis (also semimajor axis) a applies to ellipses and hyperbolas. ... The astronomical unit (AU or au or a. ... This article is about several astronomical terms (apogee & perigee, aphelion & perihelion, generic equivalents based on apsis, and related but rarer terms. ... This article is about several astronomical terms (apogee & perigee, aphelion & perihelion, generic equivalents based on apsis, and related but rarer terms. ... The orbital period is the time it takes a planet (or another object) to make one full orbit. ... In astronomy, a Julian year is a unit of time defined as exactly 365. ... The orbital speed of a body, generally a planet, a natural satellite, an artificial satellite, or a multiple star, is the speed at which it orbits around the barycenter of a system, usually around a more massive body. ... Inclination in general is the angle between a reference plane and another plane or axis of direction. ... A degree (in full, a degree of arc, arc degree, or arcdegree), usually symbolized °, is a measurement of plane angle, representing 1／360 of a full rotation. ... The Longitude of the ascending node () is one of the orbital elements used to specify the orbit of an object in space. ... The argument of the perihelion is one of the orbital elements describing the orbit of a planet. ... In the study of orbital dynamics the mean anomaly is a measure of time, specific to the orbiting body p, which is a multiple of 2π radians at and only at periapsis. ... For the majority of numbered asteroids, almost nothing is known apart from a few physical parameters. ... Unsolved problems in physics: What causes anything to have mass? Mass is a property of a physical object that quantifies the amount of matter and energy it is equivalent to. ... Density (symbol: ρ - Greek: rho) is a measure of mass per volume. ... Gravity is a force of attraction that acts between bodies that have mass. ... Space Shuttle Atlantis launches on mission STS-71 In physics, for a given gravitational field and a given position, the escape velocity is the minimum speed an object without propulsion, at that position, needs to have to move away indefinitely from the source of the field, as opposed to falling... In astronomy, a rotation period is the time an astronomical object takes to complete one revolution around its rotation axis. ... Asteroids are assigned a type based on spectral shape, color, and sometimes albedo. ... In astronomy, absolute magnitude is the apparent magnitude, m, an object would have if it were at a standard luminosity distance away from us, in the absence of interstellar extinction. ... Albedo is a ratio of scattered to incident electromagnetic radiation power. ... The geometric albedo of an astronomical body is the ratio of its total brightness at zero phase angle to that of an idealised fully reflecting, diffusively scattering (Lambertian) disk with the same cross-section. ... Fig. ... In ancient times, only the Sun and Moon, a few hundred stars and the most easily visible planets had names. ... In astronomy, a resonant Trans-Neptunian Object is a Trans-Neptunian Object (TNO) in mean motion orbital resonance with Neptune. ... A trans-Neptunian object (TNO) is any object in the solar system that orbits the sun at a greater distance on average than Neptune. ... Artists rendering of the Kuiper Belt and hypothetical more distant Oort cloud. ... May 23 is the 143rd day of the year in the Gregorian calendar (144th in leap years). ...

2001 KP₇₇ has the highest, and thus reddest measured B-V color index of any TNO. On April 19th, 2002, 2001 KP₇₇ set a TNO record B-V of 1.544. In the visible spectrum 2001 KP₇₇ would appear an orange-brown depending on its albedo. In astronomy, the color index is a simple numerical expression that determines the color of an object, which in the case of a star gives its temperature. ... A trans-Neptunian object (TNO) is any object in the solar system that orbits the sun at a greater distance on average than Neptune. ... The visible spectrum (or sometimes optical spectrum) is the portion of the electromagnetic spectrum that is visible to (can be detected by) the human eye. ... Color is an important part of the visual arts. ... Albedo is a ratio of scattered to incident electromagnetic radiation power. ...

Based on an absolute magnitude (H) of 6.93, 2001 KP₇₇ is estimated to be between 110 - 240km in diameter.
