The Star (Unabridged‪)‬

"The Star" is an 1897 apocalyptic short story by H.G. Wells.
In January (about 1900, presumably), the people of Earth awaken to the news that a strange luminous object has erupted, into the Solar System, after disturbing the normal orbit of the planet Neptune. The object is a celestial body whose luminosity is distinguishable on the sky about the constellation of Leo.
