This addon adds a full xyzv trajectory (1600-2500) for comet 19P/Borrelly There is nothing particularly incredible about Borrelly's orbit, as most distant encounters with Jupiter only slightly change its orbital inclination, with few perihelion/aphelion changes. In September 2001, the Deep Space 1 m...

This addon adds a xyzv trajectory of the Chang'e 5-T1 booster , more precisely the third stage of the Long March 3C that launched the Chang'e 5-T1 experimental lunar mission in 2014. Initially and erroneously identified to be the second stage of the F9 that launched the DSCOVR satellite, this object...

This addon adds a full xyzv trajectory (1600-2500) for comet 67P/Churyumov-Gerasimenko For many centuries, 67P remained on a orbit whose perihelion was beyond the orbit of Mars, until an encounter with Jupiter in 1959 defined its perihelion between the orbits of Earth and Mars. Has made a series of ...

A small correction in the Wild 2 ssc file, the "BlendTexture true" parameter was added, so that the specified color of the comet is filed with the texture. If you already have the addon installed, simply replace the ssc file with fixed. Remember to delete the old ssc so you don't create du...

This addon adds a full xyzv trajectory (1600-2500) for comet 81P/Wild (2) Originally this comet orbited the Sun between the orbits of Jupiter and Neptune, until a close encounter with Jupiter in September 1974 brought it into the inner Solar System. On January 2, 2004, NASA's Stardust spacecraft col...

Solar System portrait

Pluto and Charon

When will the trajectories of the rest of the natural satellites be released?
I would like the trajectories of Titan and Hyperion.

UKIRT-2017-BLG-001L UKIRT-2017-BLG-001L b is a gas giant exoplanet discovered in 2018 through gravitational microlensing. It is located 20,547 light years away from Earth, in the direction of the galactic center. It has 1.28 Jupiter masses and 1.22 Jupiter radius (estimate). It orbits its parent st...

380 light-years away from Earth, in the vicinity of Messier 45 (Pleiades), is a star G2V, known as Sunlen. It is a star that is nearly identical in size, mass, and luminosity to that of the Sun. Around it, there are 10 planets. One of them, Terranion, a world almost identical to Earth (ESI 0.98) is ...

At the moment everything is set for the scheduled release date. Just doing the final revisions.

Kepler-999 Just a hot mini-Neptune Kepler-999 b is an exoplanet orbiting the star Kepler-999, located 1,778 light-years away from Earth. It was discovered in 2016. Its orbital period is approximately 6 Earth days. Its radius indicates that it is possibly a mini-Neptune. ...............................

Unfortunately it is not possible to define alternative textures for cloud maps.

Version 2 will contain 200 rogue planets. But I will continue only after I finish the Sunlen system.

I will release the addon itself on March 21-22, exactly 9 months after the project started. By then, everything will be ready.

Trappist, some of your addons linking to Drive are no longer accessible. Possibly the files have been expired or removed.

The atmospheric parameters of all planets (those with an atmosphere) have been updated!

This addon adds 30 fictional rogue planets scattered across the Milky Way. Each rogue planet is at random positions in the galaxy, with varying distances, from the nearby of the Solar System to thousands of light years away. Each has a different radius, oblatness, and period of rotation. Some contai...
