Challenge #5


The goal of this challenge is to find the best binary planet in the given galaxy. Note: my definition of a binary is where the ratio of mass between the primary and secondary objects is closer than 20:1. So please check the masses of the objects before posting.

The galaxy to search in is RG 0-7-1860209-74

You must make your submission by 23:59 UTC on Wednesday 4 September.

Your submission must contain the location of the object and at least one but no more than three screenshots. At least one screenshot must show both worlds from space. You may only make one submission. If you would like to change your submission after you have made it, simply edit your original post and replace the old submission with the new one.

The winner of the challenge will be chosen by popular vote. As soon as the submission period ends, the voting period will begin. The voting period will last for exactly 3 days. I will announce the winners after the end of the voting period.

All forum members are encouraged to vote on the submissions made by the participants. To vote, make a post in which you rate each entry on a scale of 0-10, with 10 being the best. Challenge participants may not rate their own entry. Challenge participants may abstain from voting if they want to (you don't have to vote).

Before you start the challenge, please verify that your universe is consistent with the one most others are using by visiting the test planet below and making sure it is the same one that is posted here. If it is not, then you might have modified your SpaceEngine galaxy models from their original state. In that case, you might want to install a separate 0.9.7.0 for doing challenges with (you can skip the planet textures and spacecraft models to keep it small).


And as always, remember to post about any really extraordinary things you find while doing your challenge in an appropriate thread (such as the image dump) and mention its location and that you found it while hunting for this challenge, as you could win an award for it.

Two totally different worlds bound together. ((click for full res))

An eclipse can look beautiful from each one...

Two questions here for clarification.

1. How do I calculate the mass to see if it's a 20:1 ratio or closer? Most binary planets that I see are pretty close in mass anyway.

2. Does it count if the barycenter is within one of the planets like in this example?

Note: This is NOT my submission, besides I think the masses might be too far apart to count and this is too poor of a screenshot to use for a submission.

You divide the larger mass by the smaller mass, and if the result is 20 or less then it's valid.

You've already read my definition of a binary planet. That definition is complete.

Here's my submission, Binary Terras with life.



One that is thriving with life......


...the other, a nearly lifeless desert world.


Also, while hunting around, I found a rare binary evaporating pair of planets. I posted about it in the bug report thread because of graphical glitches that were happening.

Here's the location for that one:

Hm, are we going to continue with just two entrants? I guess it's not easy to find a good looking binary pair of planets. Or maybe the deadline can be extended.

Yeah it would certainly resemble Arrakis if the ground had a sandy texture rather than a rocky texture.

These two planets are about as double as you can get - 1.689 and 1.539 Earth Masses.

My humble submission to this challenge :



NB : I'm not so good as others at screenshot tongue
First of all this two one are relatively "close" : 277717km... Less than Earth - Moon


Both diameter are quite close (20179km and 20165k) and mass are at a 2.43 ratio. The "planet" is just more dense than it's moon. The moon as also a thin ring.


They both are frozen (aroud 160°K) and have both a light atmosphere (0.4 and 0.0004 atm)


last to say, the "moon" is tidally locked, and it's small excentricity (0.007) generate a small precession effect, making the main planet "woble" in the sky when time is accelerated.

Orbital period of the couple is 4 years, but rotation period is 7.997 days for both (and obvisouly orbital period of the moon is 7.997 days too)

Edit : Sorry for the fourth screenshot, forgot about this rule while posting ^^'
