NGC 281, IC 11 or Sh2-184 is a bright emission nebula and part of an H II region in the northern constellation of Cassiopeia and is part of the Milky Way's Perseus Spiral Arm.
 This 20×30 arcmin sized nebulosity is also associated with open cluster IC 1590, several Bok globules and the multiple star, B 1.
 It collectively forms Sh2-184, spanning over a larger area of 40 arcmin.
 A recent distance from radio parallaxes of water masers at 22 GHz made during 2014 is estimated it lies 2.82±0.20 kpc.
 (9200 ly.)
 from us.
 Colloquially, NGC 281 is also known as the Pacman Nebula for its resemblance to the video game character.
38 Arietis (abbreviated 38 Ari) is a variable star in the northern constellation of Aries.
 "38 Arietis" is the Flamsteed designation.
 It was once designated 88 Ceti, forming part of the neighboring constellation of Cetus.
 With an apparent visual magnitude of +5.18, it is bright enough to be viewed with the naked eye.
 The measured annual parallax shift of 27.52 mas is equivalent to a distance of approximately 119 ly from Earth.
41 Arietis (abbreviated 41 Ari) is a binary star in the northern constellation of Aries.
 "41 Arietis" is the Flamsteed designation.
 It does not possess a Greek letter Bayer designation, since this star was once part of the now-obsolete constellation Musca Borealis, but is sometimes designated "c Arietis".
 With an apparent visual magnitude of 3.63, this star is readily visible to the naked eye.
 It has an annual parallax shift of 19.69 mas, which indicates the distance to this star is 166 ly .
The Cienega Valley AVA is an American Viticultural Area located in western San Benito County, California, United States.
 It is part of the larger Central Coast AVA.
 The valley was once a major source of wine grapes for Almaden Vineyards before it was acquired by Constellation Brands in 1987.
 Approximately 1100 ft above sea level, the valley floor is divided by the San Andreas fault.
 Soil on the east side of the fault is predominantly granite and sandstone, whereas soils on the west side of the fault are predominantly granite and limestone.
In astronomy, an asterism is any pattern of stars recognized in the Earth's night sky.
 It may be part of an official constellation or it may be composed of stars from more than one constellation.
 Asterisms are composed of stars which, although visible in the same general area of the sky as viewed from Earth, are located at very different distances from Earth, at great distances from each other.
 Many asterisms are simple shapes composed of a few bright stars, making them easy to identify, and particularly useful to people who are familiarizing themselves with the night sky.
The San Benito AVA is an American Viticultural Area located in San Benito County, California.
 It is part of the larger Central Coast AVA.
 San Benito has a moderate climate with cooling breezes from the Pacific Ocean arriving via gaps between the Gabilan Range and the Santa Lucia Mountains.
 The region was once the principal source of grapes for Almaden Vineyards before the business was acquired by Constellation Brands in 1984.
Epsilon Arietis (ε Ari, ε Arietis) is the Bayer designation for a visual binary star system in the northern constellation of Aries.
 It has a combined apparent visual magnitude of 4.63 and can be seen with the naked eye, although the two components are too close together to be resolved without a telescope.
 With an annual parallax shift of 9.81 mas, the distance to this system can be estimated as 330 ly , give or take a 30 light-year margin of error.
Aries is one of the constellations of the zodiac.
 It is located in the northern celestial hemisphere between Pisces to the west and Taurus to the east.
 The name Aries is Latin for ram, and its symbol is (Unicode ♈), representing a ram's horns.
 It is one of the 48 constellations described by the 2nd century astronomer Ptolemy, and remains one of the 88 modern constellations.
 It is a mid-sized constellation, ranking 39th overall size, with an area of 441 square degrees (1.1% of the celestial sphere).
Vela is a constellation in the southern sky.
 Its name is Latin for the sails of a ship, and it was originally part of a larger constellation, the ship "Argo Navis", which was later divided into three parts, the others being Carina and Puppis.
 With an apparent magnitude of 1.8, its brightest star is the hot blue multiple star Gamma Velorum, one component of which is the brightest Wolf-Rayet star in the sky.
 Delta and Kappa Velorum, together with Epsilon and Iota Carinae, form the asterism known as the False Cross.
 1.95-magnitude Delta is actually a triple or quintuple star system.
Epsilon Ophiuchi (ε Ophiuchi, abbreviated Epsilon Oph, ε Oph), also named Yed Posterior, is a red giant star in the constellation of Ophiuchus.
 Located less than five degrees south of the celestial equator in the eastern part of the constellation, it forms a naked eye optical double with Delta Ophiuchi (named "Yed Prior").
 With an apparent visual magnitude of 3.220, the star can be seen with the naked eye from most of the Earth under suitably dark skies.
 Parallax measurements yield an estimated distance of 106.4 ly from the Sun.

Question: What is the area of the constellation of which Epsilon Arietis is a part?
Answer: 441 square degrees
