planetary-and-exoplanetary-dataset 🌃

Description:

This repository is created for analyzing planetary and exoplanetary datasets and extract important information as there was no combined dataset available that has all the information.

NOTE: The analysis of the data is done using the Jupyter Notebook in order to improve data visualization.

Datasets:

The information is extracted from the following datasets:

• Stellarium
• Skyfield
• HYG dataset
• Exoplanets dataset

Information collected:

You can find the following headers in the dataset:

hip	ra(hms)	dec(dms)	ra(deg)	dec(deg)	magnitude	xy position	constellation names	distance(pc)	mass(ju)	radius(ju)
67522	+13 50 6.000000480003109	-40 50 9.000067200005768	207.525	-40.835833	9.7900	[33.016166527468506, -1.384613543882283]	---	127.2700	5.000000	0.898400

Description of the files in the dataset:

Stellarium

• constellation_names.csv : contains abbreviation and full name of all the constellations
• constellations_art.csv : contains hip value and x y position of three boundary stars of each constellation
• constellations_hip.csv : contains the details about connections of stars in a constellations. example: [1,2,3,4,5,6], here 1 and 2 are connected, similarly 3, 4 and 5, 6 are connected
• ssystem_major.csv : contains orbits and physical characteristics of different planetary bodies
• ssystem_minor.csv : contains orbits and physical characteristics of different planetary bodies
• base_locations.txt : it describes various locations on earth

Skyfield

The values of HIP, RA and Dec were obtained from hip_main.dat file obtained from Skyfield:

• hip_main.dat : it is one of the largest dataset and conatins some of the most important information like:

  • hip values
  • ra (hms) and dec (dms) values
  • ra and dec values in degrees
  • magnitude of stars

Exoplanets

Further data has been analysed and added using the exoplanets catalog

• exoplanet.eu_catalog.dat : contains information like ra, dec, distance, radius and more for 4870 exoplanets

HYG dataset

• hygdata_v3.csv : contains information like hip values, distance and more

Additional functionalities:

Some of the useful functionalities that are provided in this repository are:

get l and b values (galatic coordinates) from hip values
