It's Corona. but It's Not A Virus, Not A Part of Sun Either. It's A Constellation! Corona Borealis!

Hello, hello, hi Twiskies! It's constellation day again! The constellation we're gonna discuss today isssss.... (dramatic effect) Corona Borealis!

Okay, story time first hehehe. The first time I found out about this constellation is when I was still in high school. It was when I'm starting to "drown" myself into astronomy stuff. It's kinda funny and embarrassing though, the fact that I was find out this constellation when I tried to search a cool nickname for a game username that related to stars so people could notice that this cool girl is into astronomy. That day, Corona Virus already started to spread in China and I was like "Are you kidding!? There's a constellation called Corona!"

Okay moving on!

Twiskies! you know what? the name "Corona Borealis" itself has a meaning! And it's not a silly prediction about Corona Virus hahaha. Corona Borealis means "The Northern Crown!". Wanna know why it called The Northern Crown? It's because the location and the shape of the constellation itself! Corona Borealis located in northern sky and it has a semicircle shape that make it look like a crown! But you know what else, Twiskies? There's something even more interesting about this constellation! Read the all the article if you want to find out, because I'm gonna tell that at the end hehehehe *evil laugh*

Twiskies, Corona Borealis Lies between the Hercules and Boötes constellation just like the picture above. Corona Borealis looks so tiny winy compared to both constellations, right? Almost like it's their baby! hahahaha. Okay moving on! For more specifically, this constellation is nestled between Boötes to the west, Hercules to the east. Also, Corona Borealis belongs to the Ursa Major family of constellations, along with Coma Berenices, Boötes, Camelopardalis, Canes Venatici, Draco, Leo Minor, Lynx, Ursa Major and Ursa Minor. As for its distance, Corona Borealis is 3.000 years apart form our Earth!

Alpheca (Alpha Coronae Borealis): Alpha Coronae Borealis is the brightest star in Corona Borealis, located 75 light-years away. This eclipsing binary system varies between magnitudes 2.21-2.32 over 17.36 days. The primary is a white A0V star with a dusty disk possibly containing forming planets, while its companion is a yellow G5 star. Both likely belong to the Ursa Major Moving Group.

Nusakan (Beta Coronae Borealis)Beta Coronae Borealis is a spectroscopic binary that has a period of 10.5 years. They're called for a star in the Canes Venatici constellation's Cor Caroli system. Beta Coronae Borealis is 114 light years away from our solar system. It is the second-brightest star in Corona Borealis. The traditional name, Nusakan, is derived from the Arabic an-nasaqan, which means "the (two) series."

Gamma Coronae Borealis: Gamma Coronae Borealis is a close binary star that orbits in 91 years. The system's two components are only 0.2 inches apart. Gamma Coronae Borealis is categorized as a Delta Scuti variable (also known as a dwarf Cepheid), a star whose brightness varies due to both radial and non-radial surface pulsations. The star's apparent magnitude varies from 3.80 to 3.86 during a period of 0.03 days (43 min and 12 sec).

Zeta Coronae Borealis: Zeta Coronae Borealis is another double star in this constellation. It consists of a pair of blue and white stars that are 7.03'' apart. The system is about 220 light years from the solar system.

T Coronae Borealis (Blaze Star): This is the interesting one what I mentioned earlier, Twiskies! This star is a recurrence nova, often known as the Blaze Star! The known eruptions were in the years 1217, 1787, 1866, and 1946. The outburst occurs once every 80 years, making it predictable. The astronomers predicted the other nova would happen in September 2024. But until now we're still waiting! Maybe it'd happens in 2026 or 2027? let's just wait and see! Also, astronomers predicted that we might could see the nova with naked eye! If that day comes, wanna watch it together, Twiskies? hehehe

Rho Coronae Borealis: Rho Coronae Borealis is a yellow dwarf star having an apparent magnitude of 5.4. It corresponds to the spectral class G0-2Va and is regarded as a solar twin, with nearly the same mass, brightness, and radius as the Sun. In 1997, a planet was identified within the star's orbit. Rho Coronae Borealis is 56.2 light-years away.

R Coronae Borealis (Fade-Out Star): It is a yellow supergiant located 6,000 light-years away. This variable star dramatically dims from magnitude 5.71 to 14.8 at unpredictable intervals when carbon dust clouds form in our line of sight, then brightens again as the dust disperses. Due to these spectacular brightness variations, it's known as the Fade-Out Star or Reverse Nova.

Kappa Coronae Borealis: Kappa Coronae Borealis is an orange subgiant of the spectral class K1Iva located roughly 101.5 light years from Earth. It has an apparent magnitude of 4.82. A massive planet was identified in the star's orbit in 2007.

  2. Corona borealis means the northern crown, huh? Is there any correlation between it with the cold duke from the north? Please make a conspiration theory about it😣
