Kepler 1625b

Post #1by Anthony_B_Russo10 » 04.10.2018, 11:39

This is just Keller 1625b and its potential exomoon. The star isn't here since I can not place it in its correct position, only in a similar position. But the planet and its moon have textures and defined orbits. I just need help placing the star correctly.

Here's some code I quickly pulled together for the star Kepler-1625 b. (Note that Kepler stars have a hyphen between the "Kepler" and the number.)

Code: Select all

"Kepler-1625"
{
   RA 295.4293342
   Dec 39.8865275
   Distance 8024
   AppMag 15.7627 # using G-mag because V-mag is unavailable
   SpectralType "G5IV" # guess, from mass, radius, luminosity
   Radius 1662723
}

Here's your addon packaged so that it can be unzipped into the extras directory for easier installation.

Hi,

After downloading and installing this pack of Kepler-1625 (without none change), here is the result :

Look at the given distance !!! :insane:

=> It is by doubting everything that one approaches the truth !

The distance to Kepler-1625 is not well known. It has been estimated to be anywhere from 4,000 LY to 8,000 LY. 2.46 Kpc (the distance shown) corresponds to ~8 KLY, the upper limit. For distances above some value, Celestia automatically converts LY to pc on the display.

For example, the preprint of
The nature of the giant exomoon candidate Kepler-1625 b-i
by René Heller
which can be downloaded from https://arxiv.org/pdf/1710.06209.pdf
estimates
Kepler-1625 (KIC 4760478, KOI-5084), at a distance of
2181 +332 / -581 pc, has been classified as an evolved G-type star
