    New observations reveal Trojan asteroid 624, Hektor

    Area of Science:

    • Astronomy and astrophysics
    • Planetary science

    Background:

    • Asteroid 624, Hektor is a Trojan asteroid.
    • Its rotational light curve exhibits high amplitude, suggesting unusual characteristics.

    Purpose of the Study:

    • To investigate the cause of the high amplitude in Hektor's rotational light curve.
    • To assess the physical characteristics and formation hypothesis of asteroid 624, Hektor.

    Main Methods:

    • Analysis of new observational data of asteroid 624, Hektor obtained in April 1979.
    • Interpretation of rotational light curve data to infer object shape and surface properties.

    Main Results:

    • The high amplitude of Hektor's rotational light curve is attributed to its elongated shape.

    Related Experiment Videos

  • Observations rule out albedo variations as the primary cause for the light curve's amplitude.

    • Conclusions:

    • Asteroid 624, Hektor possesses a significantly elongated shape.
    • The findings support the hypothesis of Hektor being a compound asteroid formed from a collision between two similarly sized Trojans, offering insight into planetary accretion.
