WASP-55
star in the constellation Virgo
WASP-55 is a G-type main-sequence star about 954 light-years away in the constellation Virgo. The star is much younger than the Sun at approximately 1.1+0.8−0.6 billion years. WASP-55 is similar to the Sun in concentration of heavy elements.
A multiplicity survey in 2016 found one candidate stellar companion to WASP-55 at a projected separation of 4.435″±0.018″. Follow-up observations in 2017 were unable to confirm if the suspected companion red dwarf star, with a temperature of 3,340±90 K, is gravitationally bound to WASP-55 or not. It was confirmed in 2019 using Gaia DR2 data.
Planetary system
In 2012 a transiting hot Jupiter planet, WASP-55b, was detected on a tight, circular orbit.
“WASP-55” enters the record as star in the constellation Virgo. Crown Archives preserves that source wording while asking what WASP-55, star and constellation can confirm, complicate or overturn.
Why this record matters
“WASP-55” is worth following because a concise public description often conceals a longer documentary argument. Here, WASP-55, star and constellation provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q4052858. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2016, 2017, 2019 and 2012.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. 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.
