Astrology is the study of the movements and relative positions of celestial objects as a means for divining information about human affairs and terrestrial events.

Astrology has been dated to at least the 2nd millennium BCE, and has its roots in calendrical systems used to predict seasonal shifts and to interpret celestial cycles as signs of divine communications.

Many cultures have attached importance to astronomical events, and some – such as the Indians, Chinese, and Maya – developed elaborate systems for predicting terrestrial events from celestial observations.

Western astrology, one of the oldest astrological systems still in use, can trace its roots to 19th-17th century BCE Mesopotamia, from which it spread to Ancient Greece, Rome, the Arab world and eventually Central and Western Europe.

Contemporary Western astrology is often associated with systems of horoscopes that purport to explain aspects of a person's personality and predict significant events in their lives based on the positions of celestial objects; the majority of professional astrologers rely on such systems.

Astrological compatibility (synastry) is the branch of astrology that studies relationships by comparing natal horoscopes.

A natal horoscope is a chart or map of the angles of the planets in the Solar System and their positions in the zodiac at the exact time of a person's birth.

These angles represent the positive and negative relationships between the planets.

These relationships describe the relationship between the two people under consideration.

A planet is an astronomical body orbiting a star or stellar remnant that.

is massive enough to be rounded by its own gravity,

Astrophysics is the branch of astronomy that employs the principles of physics and chemistry "to ascertain the nature of the heavenly bodies, rather than their positions or motions in space." Among the objects studied are the Sun, other stars, galaxies, extrasolar planets, the interstellar medium and the cosmic microwave background.

Their emissions are examined across all parts of the electromagnetic spectrum, and the properties examined include luminosity, density, temperature, and chemical composition.

Because astrophysics is a very broad subject, astrophysicists typically apply many disciplines of physics, including mechanics, electromagnetism, statistical mechanics, thermodynamics, quantum mechanics, relativity, nuclear and particle physics, and atomic and molecular physics.

Asteroids are minor planets, especially those of the inner Solar System.

The larger ones have also been called planetoids.

These terms have historically been applied to any astronomical object orbiting the Sun that did not show the disc of a planet and was not observed to have the characteristics of an active comet.

As minor planets in the outer Solar System were discovered and found to have volatile-based surfaces that resemble those of comets, they were often distinguished from asteroids of the asteroid belt.

In this article, the term "asteroid" refers to the minor planets of the inner Solar System including those co-orbital with Jupiter.
