scheme; system (a group of independent but interrelated elements comprising a unified whole)
Meronyms (parts of "solar system"):
interplanetary medium (interplanetary space including forms of energy and gas and dust)
Meronyms (members of "solar system"):
Venus (the second nearest planet to the sun; it is peculiar in that its rotation is slow and retrograde (in the opposite sense of the Earth and all other planets except Uranus); it is visible from Earth as an early 'morning star' or an 'evening star')
Uranus (a giant planet with a ring of ice particles; the 7th planet from the sun has a blue-green color and many satellites)
Sun (the star that is the source of light and heat for the planets in the solar system)
Saturn (a giant planet that is surrounded by three planar concentric rings of ice particles; the 6th planet from the sun)
Pluto (a large asteroid that was once thought to be the farthest known planet from the sun; it has an elliptical orbit)
major planet; planet ((astronomy) any of the nine large celestial bodies in the solar system that revolve around the sun and shine by reflected light; Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto in order of their proximity to the sun; viewed from the constellation Hercules, all the planets rotate around the sun in a counterclockwise direction)
outer planet ((astronomy) a major planet whose orbit is outside the asteroid belt (Jupiter, Saturn, Uranus, Neptune, Pluto))
Neptune (a giant planet with a ring of ice particles; the 8th planet from the sun is the most remote of the gas giants)
minor planet; planetoid (any of numerous small celestial bodies that move around the sun)
Mercury (the smallest planet and the nearest to the sun)
Mars; Red Planet (a small reddish planet that is the 4th from the sun and is periodically visible to the naked eye; minerals rich in iron cover its surface and are responsible for its characteristic color)
Edgeworth-Kuiper belt; Kuiper belt (a disk-shaped region of minor planets outside the orbit of Neptune)
Jupiter (the largest planet and the 5th from the sun; has many satellites and is one of the brightest objects in the night sky)
earth; globe; world (the 3rd planet from the sun; the planet we live on)
Holonyms ("solar system" is a part of...):
heliosphere (the region inside the heliopause containing the sun and solar system)
