light years,[8] but is drifting away at a rate of almost 8 km/s.[5]

HD 90089 is an F4

luminosity of the Sun from its photosphere at an effective temperature of 6,602 K,[8]
which gives it a yellowish-white hue.

HD 90089's exact age depends on the method, with X-ray giving it a young age of only 300

projected rotational velocity of 56.2 km/s,[2] and has an M0 companion separated 13" away[10] and at approximately the same distance.[11]

An

AU. The temperature of this dust is 30 K.[2]
