NGC 2362, also known as Caldwell 64, is an open cluster of stars in the southern constellation of Canis Major.

It was discovered by the Italian court astronomer Giovanni Batista Hodierna, who published his finding in 1654.

[4] William Herschel called it a "beautiful cluster", while William Henry Smyth said it "has a beautiful appearance, the bright white star being surrounded by a rich gathering of minute companions, in a slightly elongated form, and nearly vertical position".

This giant H II region is being ionized by the brighter members of the NGC 2362 cluster.

[4] NGC 2362 is a relatively young 4–5 million years in age[3] but is devoid of star-forming gas and dust, indicating that the star formation process has come to a halt.
