Halloween wiki:
>For other uses, see Halloween (disambiguation). Halloween is an observance celebrated on the night of October 31, most notably by children dressing in costumes and going door-to-door collecting candy. It is celebrated in much of the Western world, though most common in the United States, Puerto Rico, Ireland, the United Kingdom, Canada and sometimes in Australia and New Zealand. Irish, Scots and other immigrants brought older versions of the tradition to North America in the 19th century. Most other Western countries have embraced Halloween as a part of American pop culture in the late 20th century.

[h, also known as Terra, and (mostly in the 19th century) Tellus, is the third-closest planet to the Sun.

Scientific evidence indicates that the planet formed around 4.57 billion (4.57) years ago, and shortly thereafter (4.533 billion years ago) acquired its single natural satellite, the Moon.
