The belt consists of three bright and easily identifiable collinear star systems – Alnitak, Alnilam, and Mintaka – nearly equally spaced in a line, spanning an angular size of ~ 140′ (2.3°). [ 2 ]
1 sty 2023 · Orion’s Belt is one of the most familiar asterisms in the night sky. It is formed by three stars in the constellation Orion: Alnitak, Alnilam, and Mintaka. The bright blue stars are part of the hourglass-shaped constellation figure of Orion.
14 gru 2018 · The Kuiper Belt is one of the largest structures in our solar system — others being the Oort Cloud, the heliosphere and the magnetosphere of Jupiter. Its overall shape is like a puffed-up disk, or donut.
By 2006, astronomers had resolved dust discs thought to be Kuiper belt-like structures around nine stars other than the Sun. They appear to fall into two categories: wide belts, with radii of over 50 AU, and narrow belts (tentatively like that of the Solar System) with radii of between 20 and 30 AU and relatively sharp boundaries.

Solar System belts are asteroid and comet belts that orbit the Sun in the Solar System in interplanetary space. [1][2] The Solar System belts' size and placement are mostly a result of the Solar System having four giant planets: Jupiter, Saturn, Uranus and Neptune far from the sun.
The Kuiper Belt represents an enormous, donut-shaped volume of space in the outer solar system. While there are many icy bodies in this region that we broadly refer to as Kuiper Belt Objects (KBOs) or trans-Neptunian objects (TNOs), they're fairly diverse in size, shape, and color.
3 maj 2023 · Star clusters can contain anywhere from as few as a dozen stars to upwards of millions, and those stars can be spread out over a few light-years to hundreds of light-years. There are three different types of star clusters, which range in size, composition, and number of stars.
