[10] Among stars … Notably, V15 reported a period of 22.8 days for their planet f – very close to their estimate of the stellar rotation period. Within the commit message, you will find a link to the scientific publication where the data is taken from. Note that if no green band is shown in the plot, then the planet's orbit is far outside the habitable zone. This list shows all planetary and stellar components in the system.

[2]HD 219134 b befinner sig ungefär 21 ljusår från jorden. The host star is a metal-rich K3 dwarf located only 6.55 parsecs away (21 light years) in the direction of Cassiopeia. Eta Cassiopeiae is a binary star system in the northern circumpolar constellation of Cassiopeia. We focus on the HD 219134 system, which hosts multiple planets. 2011b). This table lists all links which are relevant to this particular system. This table lists all stars in the system HD 219134. [11][12] This and three additional exoplanets; one super-Earth (designated c and later found to be rocky as well), one Neptunian world (d), and one Jovian world (e); were deduced using HARPS-N radial velocity data by Motalebi et al. 2009). HD 219134 b has a size of about 1.6 R ⊕, and a density of 6.4 g/cm 3 and orbits at 21.25 light-years away. The limit is considered to be magnitude 6 for most observers. It is in a 2:1 resonance with the warm N-class planet Esker (HD 219134 g), making a full revolution in around 188 days, and was discovered in 2039 CE via the radial velocity method. The following plot shows the approximate sizes of the planets in this system This is consistent with a rocky, Earth-like composition. HD 219134 is an orange K-class star (K3V) in the constellation Cassiopeia, and only about half the distance, at 21.25 light years, as TRAPPIST-1 (about 40 light years out). Transits of the second planet were detected in 2017. Spitzer observations allowed us to detect the transit of the planet in front of the star making HD 219134 b the nearest known transiting planet to date. The planetary system around HD 219134 was discovered independently by teams using HARPS-N and APF, who announced four-planet and six-planet solutions respectively. (2015). If the actual C/O ratio of HD 219134 was outside the range of 0.25–0.75, our calculated disc chemistry could significantly differ.
