Which heavenly object's english name is derived from the latin for 'the heavenly father'?
X are the hottest, most sultry days of summer. X can also define a time period or event that is very hot or stagnant, or marked by dull lack of progress. The name comes from the ancient belief that Sirius, in close proximity to the sun was responsible for the hot weather. The afternoons would be particularly unbearable
Give me X On 14 March 1930, Falconer Madan read the story of the new planet's discovery in The Times, and mentioned it to his granddaughter Venetia. She suggested the name X — the Roman God of the Underworld who was able to make himself invisible — and Falconer Madan forwarded the suggestion to astronomer Herbert Hall Turner, who cabled his American colleagues at Lowell Observatory. Tombaugh liked the proposal because it started with the initials of ____ Lowell who had predicted the existence of X. On 1 May 1930, the name X was formally adopted for this new celestial body
What's X? Discovered on September 23, 1846, X was the first planet found by mathematical prediction rather than by empirical observation. Unexpected changes in the orbit of Y led Alexis Bouvard to deduce that its orbit was subject to gravitational perturbation by an unknown planet. X was subsequently observed by Johann Galle within a degree of the position predicted by Urbain Le Verrier
X and Y Many civilizations over thousands of years have portrayed the constellation of X as a Y. One theory is that the Sun was among its stars in Midsummer, during which time the Y of the Egyptian desert left their accustomed haunts for the banks of the Nile, where they could find relief from the heat in the waters of the inundation.

Who is X? One day X fell in love with a princess of an island he was passing, but her father refused to let his daughter go and, thus, was determined to keep X away from the princess. The king did so by blinding X, thus not letting him hunt and amaze the woman. X traveled to the Sun which healed his eye, and decided to lay off the king (who later died from a war) and pursued his hunting. He became great friends with Artemis, who favored X greatly for his modesty and superb skill at hunting. One day Apollo was jealous that the two were great friends, and sent a harsh scorpion at him and stung his heel. eus decided that X should be put in the stars, and the scorpion should always chase him
X and Y The two stars actually lie three light-years apart. While their proper motions show they move together as members of the Ursa Major Moving Group, it was not believed that they formed a true visual binary star system that interacts gravitationally, just an optical binary. However, in 2009, a detailed survey of the system revealed that not only was X also a binary, bringing the total number of stars in the system to six (Y is actually a pair of binary stars), but that the entire system is gravitationally bound
