99942 Apophis is a NEO/PHA discovered in 2004-Jun-19. Initially estimated to have a 2.7% chance of impacting Earth in 2029, subsequent refinement of its orbit ruled out any possibility of impact within the next 100 years. On 2029-Apr-13, Apophis will safely pass within 31,700 km of the Earth's surface.
NASA's OSIRIS-APEX spacecraft is already on its way to Apophis. Another mission, ESA's Ramses, will be launched in 2028.

This Apophis model is based on radar observations from 2012-2013, which are reported in the 2018 study.

This addon adds the seven target main-belt asteroids of the planned UAE's MBR Explorer mission.
Scheduled to launch in March 2028, MBR Explorer will flyby over six asteroids between 2030 and 2033, with a rendezvous with 269 Justitia in 2034, in addition to deploying a Justitia lander.
The presence of tholins on Justitia's surface makes it an attractive target, given that it is a possible TNO that has migrated into the asteroid belt.

In numerical order, the seven asteroids are:

- 269 Justitia
- 623 Chimaera
- 10253 Westerwald
- 13294 Rockox
- (23871) 1998 RC76
- (59980) 1999 SG6
- (88055) 2000 VA28

Orbital parameters are from JPL HORIZONS. Includes light curve models for Justitia, Chimaera and 1999 SG6 from DAMIT database. Special thanks to pedro_jg for converting these models to CMOD and for obtaining color indices for the asteroids!

This addon adds the target asteroids of the NASA's Lucy mission. Launched 2021-Oct-16, Lucy will flyby 2 main-belt asteroids and 6 Jupiter trojans during its 12-year mission.

The trojans are located at Jupiter's L4 and L5 points, orbiting in front or behind the planet. They are targets of interest given their primitive nature, being "fossils" of planetary formation in the early history of Solar System. In general, trojans have a low albedo and a reddish spectrum.

In numerical order, the Lucy targets are:

- 617 Patroclus and its satellite/companion, Menoetius (binary trojan)
- 3548 Eurybates and its satellite, Queta (trojan)
- 11351 Leucus (trojan)
- 15094 Polymele and its unnamed satellite, nicknamed "Shaun" (trojan)
- 21900 Orus (trojan)
- 52246 Donaldjohanson (MBA, possible binary?)
- 152830 Dinkinesh and its satellite, Selam (MBA)

This is a combination of the best and most recent physical and rotational parameters of these asteroids based on papers. The SSC files were originally created by pedro_jg, SevenSpheres and DaveBowman2001, and modified by me to include TCT colors and update some physical and rotational parameters, such as for Leucus, Orus and Donaldjohanson.

The Dinkinesh addon was made by Itzlmcool and domi9, and initially uploaded to mobi site.
