(277810) 2006 FV35, provisional designation 2006 FV35, is a sub-kilometer near-Earth asteroid in the dynamical Apollo asteroid group, discovered by Spacewatch at Kitt Peak National Observatory, Arizona, on 29 March 2006. [1] It is a quasi-satellite of Earth. [5] It is also notable for having a low delta-v requirement for rendezvous. [4] Although its orbital period is almost exactly 1 year, the orbit of 2006 FV35 has a high eccentricity which causes it to cross the path of Venus.
2006 FV35 was discovered on 29 March 2006 by astronomer J. V. Scotti using the Spacewatch 0.9 meter telescope at Kitt Peak National Observatory. Scotti was working as a part of the Spacewatch survey project, and the asteroid's discovery was announced by the Minor Planet Center (MPC) in a Minor Planets Electronic Circular on 31 March. [6] It was given the number (277810) by the MPC on 17 May 2011. [7] As of November 2025, it remains unnamed; 2006 FV35 is its provisional designation. [2] [1]
2006 FV35 orbits the Sun with a semi-major axis of 1.001 astronomical units (AU), taking 366.04 days—almost exactly one year—to complete one orbit. It is classified as a near-Earth asteroid (NEA) and an Apollo asteroid; [2] Apollo asteroids cross Earth's orbit and have semi-major axes above 1 AU. [8] It has a low orbital inclination of 7.1° from the ecliptic plane and a high orbital eccentricity of 0.377, intersecting the orbit of Venus. Due to its high eccentricity, its distance to the Sun varies from 0.62 AU at perihelion to 1.38 AU at aphelion. [2] [5] : 491
2006 FV35 is a quasi-satellite of Earth, participating in a 1:1 mean-motion resonance with the planet. [5] : 488–489 Quasi-satellites have principal libration angles [a] that librate around 0°, [5] : 488 appearing to distantly orbit Earth from its perspective despite never entering its Hill sphere. [9] Currently, 2006 FV35's principal resonant angle librates with an amplitude of 25° and a period of about 200 years. Its quasi-satellite loop is relatively wide, remaining about 0.64 AU distant from Earth. [5] : 491 All of Earth's known quasi-satellites are temporary, and their orbits will eventually evolve into other NEA dynamical configurations in the future. [9] 2006 FV35 has been a quasi-satellite for about 10,000 years, and will remain one for 800 more years before a close encounter with Venus (within 0.05 AU) perturbs it from that state. Thereafter, it will likely remain an Earth co-orbital, transitioning between horseshoe, tadpole, and passing configurations. [5] : 492
2006 FV35's physical properties are poorly known. Using its absolute magnitude of 21.7, it has a calculated diameter of 130–300 metres (430–980 ft) for an assumed albedo of 0.20–0.04. [3] : 2989 [b]
With a semi-major axis of almost exactly 1 AU, 2006 FV35 has a relatively low transfer energy from Earth. The delta-v required to transfer to the asteroid varies between 11 and 13 km/s; this change in delta-v oscillates over an approximately 200-year period with the current transfer cost near its maximum of 13 km/s.
