Stars Trivia

1. Aries main asterism is formed by three prominent stars, of which the brightest one is mostly referred to by the traditional name of "Hamal". This is the Arabic word for what animal?

From Quiz The Stars We Find Along The Way

Answer: Ram

The name is derived from "ras al-hamal", meaning "head of the ram". The other two stars of the asterism form the "horns of the ram" (qarna al-hamal). Even though it's not as bright as some other stars in the night sky, it is one of the "navigational stars", i.e., stars that are used as a point of reference in navigation. Also, in ancient times, Hamal was the brightest star in the constellation that contained the northern vernal equinox, the point where the Sun's apparent path crosses the celestial equator from south to north, thus marking the beginning of spring in the northern hemisphere. This is the reason why the horoscope starts at Aries (although, recently, the equinox has moved to the Pisces constellation).

From Quiz Follow That Star!

Answer: It was the brightest star in the sky.

Sirius is the brightest star in the sky; in fact, it is almost twice as bright as the next brightest star, Canopus. One of the reasons it seems to be so bright is because it is close to Earth. As it is gradually getting closer each year, it will also appear to be brighter during the next 60,000 years. Scientists estimate that it will be the Earth's brightest star for the next 210,000 years. Another reason it is so bright is due to its luminosity, or intrinsic brightness.

From Quiz "A" List Stars

Answer: it's an eclipsing binary

Algol is in the constellation of Perseus and legend says that it is the eye of Medusa, whom Perseus slew. The "eye" seems to wink slowly over the course of 4 days because the fainter star moves in front of the brighter one. Although Algol is actually a three-star system, the third star does not occlude the others as seen from Earth.

From Quiz Beta Stars

Answer: Rigel

Betelgeuse is a huge red supergiant but Rigel is actually a blue supergiant. It is much brighter in absolute magnitude and a bit brighter in apparent magnitude. Rigel is considered the left foot or ankle of Orion and Betelgeuse is the right shoulder. The other two are also quite bright. Bellatrix is the left shoulder and Saiph is the right foot.

From Quiz Binary Star Systems

Answer: Two stars which orbit a common center of gravity

In a binary system, two stars orbit each other due to a common gravitational center, which is dependent on the mass on the stars. When two stars appear close together in the sky, the situation is known as an "optical double". This means that although the stars are aligned along the same line of sight, they may be at completely different distances from us. This occurs in constellations; however, two stars in the same constellation can also be part of a binary system.

From Quiz The Stars We Find Along The Way

Answer: Aldebaran

Taurus' most notable features are the Pleiades and Hyades, two of the nearest open star clusters to Earth. However, Aldebaran is not part of those. Derived from the Arabic word for "the follower", Aldebaran's name illustrates the fact that it seems to "follow" the Pleiades during the motion of the celestial sphere in the night. Although it's cooler than the Sun, is a lot more massive, and about 400 times more luminous. Therefore, it is relatively easy to observe it in the night sky, particularly between November and December in the northern hemisphere.

There are 15 equatorial constellations (those that cross the equator), including two separate parts of Serpens as one, and there are two circumpolar constellations, where the celestial poles are located in that appears to rotate around it -- the north pole is in Ursa Minor, while the south pole is in Octans. So 15 × 2 is 30.
