98943 Torifune (provisional designation 2001 CC21) is a stony near-Earth asteroid of the Apollo group, with a diameter of about 500 metres (1,600 feet).
[1] It is an upcoming flyby target of JAXA's Hayabusa2 extended mission, which will approach less than 100 km (62 mi) from the asteroid in July 2026.
[8][9] "Torifune" is an abbreviation of Ame-no-torifune, the name of a Japanese god and his ship, "which can travel safely at high speed like a bird and steady as a rock.
"[9] Observations of Torifune's infrared thermal emission by the Spitzer Space Telescope in 2005 show that it is a small asteroid with a mean diameter of 465 m (1,526 ft).
[5][6] Hayabusa2 will flyby within 100 km (62 mi) of Torifune at a very high relative speed of 5 km/s (3.1 mi/s), which will pose a challenge for the spacecraft's navigation and tracking capabilities during the encounter.
