Planetary and Exoplanetary Dataset

PROJECT

This project 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:

Information collected:

You can find the following headers in the dataset:

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
