Are there any poisonous lizards?
First of all, what is a constellation? Constellation is a combination of several stars in a certain area on the celestial sphere. Let's talk about what a star is, a celestial body that can glow and heat by its own thermonuclear fusion. The key to saying so much is this sentence: "Because of the long distance, their position changes on the celestial background can be ignored (on their own) and remain relatively static, hence the name". For example, the Big Dipper has maintained its shape for thousands of years.
Whether you can see the constellation depends only on two parameters. At the first latitude, observers can't see the celestial bodies in the constant hidden circle, for example, in Shanghai, they can't see the celestial bodies south of -59 declination; The second is the season, which is easy to understand. If you get too close to the sun, you will be drowned by the sun. Now you can see the absurdity of this statement:
Constellations can't last long. As long as it can appear, it can be observed for at least half a year according to the annual motion law of celestial bodies. Not to mention the bizarre cycle of 1 16.
Constellations were not discovered by accident. From ancient times to the present, many abandoned constellations have appeared after numerous compilation of star maps. Moreover, at least in the current map of the last century, there is no room for inserting another constellation (the clear boundary was stipulated by the International Astronomical Union in the 1930 s).
If this poisonous lizard is replaced by a comet, it still makes sense. One time in 148 is a regression cycle, which can only be observed for one hour. This is the phase of the comet relative to the sun (it should be a sun-grazing comet, close to the sun on the ecliptic), which astronomers accidentally discovered. But comets can't be called "poisonous lizards", either named after the discoverer, such as "Ikeya-Zhang Comet" or named after the year, such as "1680 Great Comet".
