Introduction

Quita's planet is fictitious, but her star isn't. Her world circles HD 164595 (also called HIP 88194, SAO 85632, and BD+29 3165) about 94 light years from here. She calls it Organ.

We've already detected a planet orbiting her sun. At 16 Earth masses, it is believed to be a Neptune-like gassy planet incapable of supporting life.

Quita calls her planet Twycotium Orbnite. It similar to Earth, but somewhat larger. It's lower density yields slightly less gravity.

Her world has two moons, Vadgi and Temich that orbit closer than our moon. They are both smaller as well. They are tidally locked (one side always faces Twicon), but only Vadgi is large enough to be spherical.

Vadgi

Temich

Mean radius 207 km
Surface area 5.38105 km2
Volume 3.72107 km3

Escape velocity 0.254 km/s

Twicon has a longer day than Earth (30.4525 hours). Quita's people divide their days into 100,000 'seconds' which are slightly longer than our seconds. They don't use time zones, prefering to reference a common planetary time instead (like our universal time zone).

This Twicon clock shows the current time there.

The top row shows Year: Month: Day. There are 320.19 Twycon 'days' in a 'year'. They divide their 'year' into 10 'months' of 32 'days' each with leap 'day' usually added every 5 'years'. The second row shows Hour: Minute: Second. There are 10 'hours' in a 'day' with 100 'minutes' per 'hour' and 100 'seconds' per 'minute'.

The diamonds represent their 'hours' starting at the top right, going clockwise. The triangles similary repersent 'minutes' and the pentegon in the middle repersents 'seconds'. The color ranges from Yellow to Green, Cyan, Blue, and finally Violet for 2 'hours', 2 'minutes', or 100 'seconds'.
