Out Solar System. Planet's positions, Sun's and Moon' s position and rise/set

SOLARSYSTEM

Our Solar System consist 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

# 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
# Eris        23.55        -11.74       96.0
