Solar System models, especially mechanical models are called orreries.
Antares Absolute and Apparent Magnitude Absolute Magnitude~ -5.2 Apparent Magnitude~ +0.60
The Heir Apparent - 2014 was released on: USA: 1 September 2014
The two types are apparent magnitude, the magnitude of a star as it appears to us, and absolute magnitude, which is what a star's apparent magnitude would be at a standard distance of ten parsecs.
Apparent magnitude: How bright something looks to us. Absolute magnitude: How bright something really is - expressed as the apparent magnitude it would have at a standard distance.

Parallax id the apparent shift in position of an object with respect to the background due to a shift in view point.
Parallax is the apparent shift in position of an object when viewed from two different locations. It is used to measure distances to nearby stars and celestial objects by observing their change in position against more distant stars.
The apparent magnitude of a celestial object is a measure of its brightness as seen from Earth. The lower the apparent magnitude, the brighter the object appears in the sky. This means that a celestial object with a lower apparent magnitude is brighter than one with a higher apparent magnitude.
The sun's apparent path through the background of stars is called the ecliptic. It is the apparent annual path that the sun follows as seen from Earth.
The sun has the greatest apparent magnitude in the sky because it is the closest star to Earth, making it appear very bright. Its proximity combined with its luminosity contribute to its high apparent magnitude compared to other celestial objects.
Apparent magnitude is a measure of how bright a celestial object appears from Earth. It is a logarithmic scale where lower numbers indicate brighter objects. Apparent magnitude takes into account the intrinsic brightness of the object as well as its distance from Earth.
Parallax is the apparent movement of an object across a background when observed from two different places.
The "ecliptic". In truth, the Sun doesn't move; the apparent motion of the Sun across the sky is caused by the Earth spinning, and the apparent motion of the Sun across the "celestial sphere" is caused by the Earth orbiting the Sun. But the plane of the Earth's orbit around the Sun is what causes the apparent motion of the Sun across the celestial sphere, so the "ecliptic" is actually the plane of the Earth's orbit.
Equinoxes are the two points among the stars where the sun's apparent annual path crosses the celestial equator. Solstices are the two points among the stars where the sun's apparent annual path reaches its extremes, north and south of the celestial equator.
The apparent movement of an object across a background when observed from two different places is called parallax.

Parallax is the apparent movement of an object across a background when observed from two different places. This phenomenon is due to the shift in the object's position relative to the background as the observer's perspective changes.
