Answer 1

Answer:

Explanation:

Mobile planetarium definition:

A portable, inflatable planetarium called the Star Dome can be used in most school gyms or halls. There is room inside for about $30$ youngsters or $25$ adults to participate in a session at once. It is $6$ meters in diameter and roughly $4$ meters high.

Planetarium:

A planetarium is a theatre designed primarily for the presentation of fun and interesting shows about astronomy and the night sky, or for instruction in celestial navigation.

The big dome-shaped projection screen, which is a defining characteristic of most planetaria, can be used to create scenes of stars, planets, and other celestial objects that look and move realistically to replicate the intricate "motions of the sky." Numerous technologies, including lasers, slide projectors, video and full dome projector systems, and precisely constructed "star balls" that combine optical and electro-mechanical technology, can be used to create the celestial vistas. Regardless of the technologies employed, the goal is typically to connect them so as to imitate an accurate relative motion of the sky. Systems of this type can be configured to imitate the sky at any moment, past or present, and frequently to show the night sky as it would appear from every place of latitude on Earth.

From the $37$-meter-tall "Planetarium No $1$" in St. Petersburg, Russia, to three-meter-tall inflatable portable domes where viewers sit on the floor, planetariums come in a variety of sizes.

The word "planetarium" is occasionally used in a generic sense to refer to other solar system-illustrating tools, such as a computer simulation or an orrery. A computer program known as "planetarium software" can display a three-dimensional depiction of the sky on a two-dimensional computer screen or in a virtual reality headset.  A member of a planetarium's professional staff is referred to as a "planetarian."
