## On Planet Proporties

Here’s the info on the size of the planet, the star, the planet’s orbit and the things that result like the number of days in a year and so on. It’s the flat data, nothing to expand much on that, which I’ll come back to later. I was going to put time keeping into this post also, but there’s a lot I want to say about that including math and what base some of the cultures use which I only figured out once I was doing the time and… but here’s the data.

**PLANET DATA**

**DAY LENGTH** 28 hours

**MASS** 2 relative Earths

**DENSITY** 5.9 g/cm³

**DIAMETER** 15,730 km

**SURFACE AREA** 777.1 million km^{2}

**ROCHE LIMIT** 2000 km

**GRAVITY AT SURFACE** 1.32 Gs

**AXIAL TILT** 18.5678°

**ARCTIC LATITUDE ** 18.5678°

**ANTARCTIC LATITUDE** 161.4322°

**UPPER TROPIC** 71.4322°

**LOWER TROPIC** 108.5678°

(In these cases, we are assuming that Polar North is 0° and the equator is 90° where as on earth it’d be the other way around. Meaning that the South Pole is 180°. May change this at a later date.)

**SUN, ORBIT AND YEAR LENGTH**

**SUN TEMPERATURE** 5900 K (Our’s is about 5800K)

**APHELION **1.36 AU aka 205,000,000 km

**PERIHELION** 1.31 AU aka 196,500,000 km

**ORBIT ****CIRCUMFERENCE**** **1,258,428,456 km

**SPEED OF PLANET ALONG ORBIT** 31.029 km/s aka 1,861.74 km/m aka 111,704.4 km/h

**ONE SHIR YEAR** 402.34 alien days OR 469.4 earth days

402 1.33 ____ = _______

307 1.015

Where the alien planet is in green and earth in red, this shows the relationship between the length of year between the two of them. This is counted in terms of alien days but doing the same in earth days gives similar results. The slight differences is due to rounding of decibel points.
