2019 QE1 has been classified by CNEOS as an (https://www.ibtimes.com/nasa-asteroid-tracker-177-foot-asteroid-swings-earth-10pm-today-2821682) Apollo asteroid
Its objective is to collect a sample of at least 60 grams (and as much as 2 kg) of the Earth-crossing Apollo asteroid
101955 Bennu and bring the sample back to Earth in 2023 for study.
It appears to have been a relatively ordinary Apollo asteroid
having a perihelion distance of 0.8AU and aphelion of 2.5AU.
Then there's the strange case of an Apollo asteroid
known as 1979 VA.
2019 QX3 has been classified by CNEOS as an Apollo asteroid
. Like the other (https://www.ibtimes.com/1214-foot-killer-asteroid-headed-towards-us-friday-will-it-hit-earth-2821203) space rocks that belong to this family of asteroids, the wide orbit of 2019 QX3 takes it around the Sun and the Earth.
Hayabusa 2's target asteroid, 1999 JU3, is an Apollo asteroid
roughly 900 meters (3,000 feet) in diameter with a period of 7V2 hours.
Gaffey's team conjectures that the Apollo asteroid
represents a chip off an old rock, a runaway fragment of a larger resident of the Hungaria region.
The agency categorized 2019 GT3 as an (https://www.ibtimes.com/nasa-asteroid-tracker-292-foot-154-foot-asteroids-skim-earth-tuesday-2821199) Apollo asteroid
The following year he bagged two more Earth-crossers - 1998 FG2, an Apollo asteroid
found on March 21st, and 1998 HE3, another Aten, discovered a month later.
Yeomans used the example of Apollo asteroid
1997 BR, whose orbit they adjusted in their models so that it would collide with the Earth in 2051.
Because the object comes within Earth's orbit, it is classified as an Apollo asteroid
. Furthermore, because the orbit's semimajor axis is just shy of 1 astronomical unit, resulting in an orbital period of a little less than one year, the asteroid is also of the Aten type.
An opportunity provided by the Apollo asteroid
Geographos seemed just the ticket, as its close approach to Earth in August 1994 would make communication with ground stations easy during and after encounter.
