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 km2

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.
