Our Solar System. Planet's positions, Sun's and Moon' s position and rise/set
Project description
SOLARSYSTEM
Our Solar System consists of:
- our Star, the Sun
- 8 Planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune
- Some dwarf Planets: Pluto, Ceres, Eris, (Haumea, Makemake, Quaoar, Sedna, Orcus, 2007 OR10, not yet included here)
- Some Centaurs: Chiron (onlyone included here)
- Many moons orbiting planets. Our Moon (Selene in Greek or Luna in Latin) is orbiting Earth
solarsystem is a library for finding position of planets around Sun or around Earth.
Also with solarsystem we can find positions around Sun/Earth of dwarf planets (only 3 planets so far) and Chiron Centaur and position of moon around Earth
Furthermore we compute sunrise/sunset, moonrise/moonset and moon phase for given place (geocoordinates).
Except all computation above with this library a set of usefull functions are included with which we can convert between coordinate systems:
- Transform spherical to rectangular projection.
- Transform rectangular to spherical projection.
- Transform ecliptic to equatorial projection.
- Transform equatorial to ecliptic projection.
- Transform eclipitc to spherical projection.
- Transform spherical to eclipitc projection.
Quick start
import solarsystem
Initialize class
H = solarsystem.Heliocentric(year=2020, month=1, day=1, hour=12, minute=0 )
Compute position of planets around sun
planets_dict=H.planets()
print('Planet',' \t','Longitude',' \t','Latitude',' \t','Distance in AU')
for planet in planets_dict:
pos=planets_dict[planet]
print(planet,' \t',round(pos[0],2),' \t',round(pos[1],2),' \t',round(pos[2],2))
# Planet Longitude Latitude Distance in AU
# Mercury 263.83 -4.06 0.47
# Venus 5.23 -3.22 0.73
# Earth 79.47 0.0 0.98
# Mars 214.38 0.49 1.59
# Jupyter 276.1 0.1 5.23
# Saturn 292.51 0.05 10.05
# Uranus 35.35 359.52 19.81
# Neptune 348.02 -1.04 29.91
# Pluto 292.75 359.33 33.88
# Ceres 290.87 -5.4 2.92
# Chiron 4.33 2.94 18.81
