Based on W. M. Keck adaptive optics observations, we found a unique and stable orbital solution, which is uncommon in comparison to the orbits of other large multiple asteroid systems studied so far. … in 2006, our team discovered a small 12-km moon in orbit around the primary. We present a composite spectrum of Trojan asteroid 624 Hektor, 0.3-3.6 μm, and models computed for the full wavelength range with the Hapke scattering theory. Hartmann, W. K. & Cruikshank, D. P. 1979, Bulletin of the American Astronomical Society New Observations of Trojan Asteroid 624 Hektor: Hektor is Elongated. The geometric albedo rises from 0.023 at 0.44 um to 0.065 at 2.5 um, and remains nearly constant out to 3.6 um. We have observed the reflectance spectrum of Hektor from 2.4 - 3.6 um, with the UKIRT/CGS4, and with other data we have constructed the spectrum from 0.3 to 3.6 um. Keck adaptive optics observations, we found a unique and stable orbital solution, which is uncommon in comparison to the orbits of other large multiple asteroid systems studied so far.
With a size of 270 km long and 200 km wide, Hektor has a bi-loped shape. The data show that there is no discernible 3-μm absorption band. The binary asteroid system 624 Hektor and Skamandrios i s a large-size-ratio binary system. (624) Hektor is the binary asteroid system which has elongated/bi-lobed primaries with a small moonlet and a rapidly rotating primary (Noll et al., 2014). Este cel mai mare asteroid troian cunoscut. evolution of our solar system. (2002). In addition observational data for the irregular shape of asteroid (624) Hektor has been obtained in the literature Kaasalainen et al. The binary Trojan asteroid (624) Hektor is the only known Trojan asteroid to possess a small satellite. The equivalent diameter of the primary 624 Hektor is 250 km, while the Based on W.M. The binary Trojan asteroid (624) Hektor is the only known Trojan asteroid to possess a small satellite. Based on W. M. Keck adaptive optics observations, we found a unique and stable orbital solution, which is uncommon in comparison to the orbits of other large multiple asteroid systems studied so far. Near-simultaneous visual and thermal IR (20-micron) photometry of the Trojan asteroid 624 Hektor is reported which was performed when the asteroid was observed nearly along its rotation axis. 624 Hektor, sau 624 Hector, este un asteroid troian al lui Jupiter descoperit de August Kopff, la 10 februarie 1907.

The binary Trojan asteroid (624) Hektor is the only known Trojan asteroid to possess a small satellite. Hartmann, W. K. 1979, Lunar and Planetary Science Conference Proceedings A special class of planetary collisions - Theory and evidence 624 Hektor, the largest Jovian Trojan, is a D-type asteroid. Distant asteroid revealed to be a complex mini geological world A study suggests that the large Trojan asteroid (624) Hektor and its small moon are products of the collision of two icy asteroids. This moon has a unique and special orbit. This video shows the location of the largest Jupiter Trojan asteroid (624) Hektor. 2001). A comparison to 624 Hektor, a D-type Trojan asteroid, is shown in Figure 2 where the albedo of Phobos from OSIRIS data is scaled to match Hektor's (Cruikshank et al.
