Data and Resource
Systems
- List of multiplanetary system came from Wikipedia
- Made some change from this list. Final list of systems see data4.csv
Planets Data
Raw planets data came from:
- Exoplanet Data Explorer
- NASA Exoplanet Archive
- Open Exoplanet Catalogue
- Extrasolar Planets Encyclopedia
Texture Data
- used .ssc files from celestia motherlode to decide which texture to use on which planets
- texture files are from celestia software
Data entries I used:
Name of the System
Name of the Star
- same of name of the system if not binary/trinary system
- system name + suffix (A/B/C) for binary/trinary systems
- I called the system consists of HD 20781 and HD 20782 'HD 20781 + HD 20782'
Radius
- used 'R_sun' for stars and 'R_jupiter' for planets
Distance to us
- for stars
Orbit distance
- for planets
- represented by Semi-Major Axis of original data
- used 'AU'
Texture
- texture files are from Celestia and The Celestia Motherlode
- mapping between planets and texture files is from Celestia
Right ascension
- for stars
- used for generating 3D universe (see here)
Declination
- for stars
- used for generating 3D universe (see here)
Apparent magnitude
- for stars
- used for calculating habitable zone (see here)
Spectral class
- for stars
- O or B or A or F or G or K or M or unknown
- used for coloring in 3D universe
- used for assigning textures to stars
Spectral type
- for stars
- e.g. G5V or K1.5IV
(Confirmed) number of planets
- for stars
- only kept confirmed planest
Day
- for planets
- how long to rotate 360 degree
- used 'day'
Year
- for planets
- how long to orbit 360 degree
- used 'year'
Inclination
- for planets
- degree of inclination
Detection Method
- for planets
- how the planets are discovered
Binary Or Trinary
- for stars
- empty not binary/trinary, actual type if binary/trinary
Mass
- for planets
- used to estimate radius of planets (see this document)
- used 'M_earth'
