(687170) 2011 QF 99 was identified as the first Uranus trojan in 2013. It is located at the L 4 Lagrangian point. A second one, (636872) 2014 YX 49, was announced in 2017. [17] 2013 ND 15 is a temporary Venusian trojan, the first one to be identified. The large asteroids Ceres and Vesta have temporary trojans. [18]
617 Patroclus (/ p ə ˈ t r oʊ k l ə s / pə-TROH-kləs) is a large binary Jupiter trojan asteroid. It is a dark D-type asteroid and a slow rotator, due to the 103-hour orbital period of its two components. It is one of five Jupiter trojan asteroids targeted by the Lucy space probe, and is scheduled for a flyby in 2033.
Asteroids in the L 4 and L 5 Sun–Mars Lagrangian points are sometimes called Mars trojans, with a lower-case t, as "Trojan asteroid" was originally defined as a term for Lagrangian asteroids of Jupiter. They may also be called Mars Lagrangian asteroids.
Lucy will provide the first high-resolution images of what these asteroids look like. Lucy is scheduled to reach the Trojan asteroids in 2027. Each of the asteroids Lucy is set to fly by differ in ...
Astronomers spotted a possible “sibling” planet that shares the orbit of another exoplanet in a system located 370 light-years away.
Lucy is a NASA space probe on a twelve-year journey to eight different asteroids. It is slated to visit two main belt asteroids as well as six Jupiter trojans – asteroids that share Jupiter's orbit around the Sun, orbiting either ahead of or behind the planet. [4] [5] All target encounters will be flyby encounters. [6]
WISE, a space telescope launched into Earth orbit in December 2009, imaged 2010 TK 7 in October 2010 while carrying out a program to scan the entire sky from January 2010 to February 2011. Spotting an asteroid sharing Earth 's orbit is normally difficult from the ground, because their potential locations are generally in the daytime sky. [ 8 ]
In the moments before NASA's DART spacecraft slammed into the asteroid Dimorphos in a landmark planetary defense test in 2022, it took high-resolution images of this small celestial object and its ...
