variable star in the constellation Aries
VZ Arietis is single, white-hued star in the northern zodiac constellation of Aries. Varying between magnitudes 5.82 and 5.89, the star can be seen with the naked eye in dark, unpolluted areas. Based upon an annual parallax shift of 5.8 mas, it is located 560 light-years from the Sun. It is moving further away with a heliocentric radial velocity of +14 km/s. The star was formerly known as 16 Trianguli, but as the star is no longer in the constellation Triangulum, this designation has fallen out of use.
In 1984, the Czechoslovak astronomer Juraj Zverko announced that the star, then called HR 830, is a variable star. It was given its variable star designation, VZ Arietis, in 1987.
This is a chemically peculiar star of type CP2 (Ap star), showing an anomalous abundance of silicon in its spectrum. It has a stellar classification of A0 V, which indicates this is an A-type main-sequence star that currently fusing hydrogen into helium in its core. This is an Alpha2 Canum Venaticorum variable with 2.7 times the mass of the Sun and about 3.1 times the Sun's radius.

Why this record matters
A short description can identify a subject without explaining its stakes. For “VZ Arietis”, the useful work is to connect “variable star in the constellation Aries” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 12, 2026. The linked authority identifier is Q1748560. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1984 and 1987.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
