Rigel (β Ori) - It is usually the brightest star in the constellation, only occasionally surpassed by Betelgeuse during its greatest maximum. With its brightness of 0.14mag, it is the seventh brightest star in the sky. It is of spectral type B8, so its blue-white color is clearly visible to the naked eye. Rigel is 78 times larger and 12,000 times more luminous than our Sun, and it is located at a distance of 860 light-years.

Betelgeuse (α Ori) - This glowing red supergiant is a semi-regular variable star, with its brightness ranging from 0.4mag to 1.3mag in a period of approximately 5.7 years. However, it appears more orange in color. Betelgeuse is one of the largest stars visible to the naked eye. If it were located at the position of the Sun, its outer edge would extend all the way to the asteroid belt. It is located at a distance of 500-600 light-years.

Alnitak (ζ Ori) - The left star of Orion's belt is actually a triple star system. Close to the main component with a brightness of 1.9 magnitude, there is a companion with a brightness of 4.2 magnitude at a separation of 2.7 arcseconds. At an angular distance of 57 arcseconds, there is another star with a brightness of 9 magnitude, which is likely only projected near Alnitak. All components have a blue-white color.

Mintaka (δ Ori) - The right blue-white star of the belt near the celestial equator. It is one of the easiest distinguishable pairs - a telescope with a diameter of at least 5 cm will be sufficient. We will see the pale blue guide of magnitude 6.9 next to the main component at a separation of 52.6". It is likely a true binary star, even though the components are separated by half a light-year. Their mutual orbital period could therefore last up to a million years. The system is located at a distance of 2,350 light-years. Additionally, the main component is a variable star, but with a very small change in brightness (around 2.2 mag).

ι Ori - nice triple star suitable even for small telescopes. Next to the main white component (2.8mag) there is a faint blue companion (7.3mag) at a separation of 11.3". Another, reddish companion (11mag) is observed at a distance of 50" from this pair. The finder also shows a wide double star Struve 747, consisting of bright components with magnitudes 4.8 and 5.7.

λ Ori - The white companions have magnitudes of 3.5 and 5.6, with a separation of 4.4". Two additional, bluish companions are located at distances of 28" and 78" from this pair, respectively. λ Ori designates the head of Orion and forms an interesting triangle with π-1 and π-2 Ori. Both of them have a magnitude of 4.

σ Ori - With a telescope with a 5 cm objective diameter, we can detect two companions to the main white component with a magnitude of 3.81. The first companion has a magnitude of 6 and is located at a separation of 41". The second companion has a magnitude of 7 and is separated by 13". In a telescope with an objective diameter of around 15 cm, a companion with a magnitude of 10 is added at a separation of 11". Another companion with a magnitude of 6 is located very close to the main component, at a distance of 0.2", but only it is physically associated with the main component.

Trapéz - The "Theta system" is located in the heart of the Great Nebula in Orion and is one of the most famous multiple stars in the entire sky. Its four stars, ranging in brightness from 5th magnitude to 8th magnitude, form a quadrilateral called the Trapezium. Several 11th magnitude stars inside and around the quadrilateral undoubtedly belong physically to the Trapezium system. What's more, within a 5' area of the Trapezium, over 400 very faint stars are hidden, extremely young objects recently born from massive clouds of gas and dust. The stars of the Trapezium are exceptionally young, approximately 30,000 years old.
