Alright, so there's a RP website I'm on that has a fairly detailed description of their solar system. However, they have no details on their planet's moons. This is something I've been trying to work out, as I want to introduce a lunar calendar of sorts to a nation I RP there. I've managed to get pretty far, but I'm not sure if my math is correct.(adsbygoogle = window.adsbygoogle || []).push({});

Also I want to make sure that with the numbers I have, the tides would be similar to Earth's, or at least not at a small-tsunami kind of level. I don't know how to figure out tides, so that's why I'm asking you guys for help.

Can anyone help me?

The current set up looks like this:

Planet in question:

Diameter: 15,670 km

Rotation Period: 24 Hr

Orbital Period: 378 Days

Mass: 9.94E+24 kg

Density: 4.9359 g/cm3

Volume: 2.01E+12 km3

Number of Moons: 2

Diameter of Moons: First moon (5,417 km), second moon (2,330 km)

I've had to fill in a bunch of information from here, since they don't exactly get into that much more details on the moon (though they go into much more detail about their system). So here are the numbers I've come up with. I've tried to make sure the orbits are stable by plugging the numbers into Universe Sandbox and running a simulation.

First moon:

Mass: 1.525812 × 10^{22}kg

Diameter: 2,330 km (was provided for me)

Distance from planet: 350,000 km (they mention that the distance of the first moon to the planet is twice the distance of our moon to Earth)

Estimated Orbit time (according to Universe Sandbox): about 18.5 days

Tidal force from first moon: 3.88205 x 10^18 N to 3.52668 x 10^18 N

Second moon:

Mass: 1.257673 × 10^{23}kg (a bit smaller than Titan)

Diameter: 5,417 km (was provided for me)

Distance from planet (semi-major axis): 700,000 km (they say that the first moon is the closest moon and I'm worried that if I go any closer the first moon would zoom off into deep space)

Orbital Eccentricity: 0.05

Estimated Orbit time (according to Universe Sandbox): about 52 days

Tidal force from second moon: 4.4448 x 10^18 N to 3.29197 x 10^18 N
