HD 224693, also named Axólotl, is a

light years from the Sun. It is drifting further away with a radial velocity of 1.5 km/s.[1]

The star HD 224693 is named Axólotl. The name was selected in the NameExoWorlds campaign by Mexico, during the 100th anniversary of the IAU. "Axólotl" means "water animal" in the native Nahuatl language and an axolotl is also a species of salamander endemic to the valley of Mexico.[7][8]

This is an ordinary

projected rotational velocity of 4.2 km/s.[6] The star is metal rich, showing a higher abundance of elements other than hydrogen and helium when compared to the Sun.[4] It has 1.3[5] times the mass of the Sun and 1.8 times the Sun's radius. The star is radiating 3.78 times the luminosity of the Sun from its photosphere at an effective temperature of 5,971 K.[1]

Planetary system

In 2006, an

Fairborn Observatory was inconclusive because data around the predicted time of transit was too sparse to rule out possible transits.[4] This exoplanet was named Xolotl, after the Aztec god of fire and lightning.[10]
