Universe Sandbox ² | Discussion / Bulk Positioning of Objects

« Last post by jimroyal on July 12, 2024, 11:53:53 AM »

Is there any way in Universe Sandbox to efficiently place and position a large number of objects?

Suppose I wanted to import this table of long-period comets:

https://en.wikipedia.org/wiki/List_of_long-period_comets

The table has names, orbital period, eccentricity, major axis, and inclination... is there a way to get this data into the program without having to manually enter all the values?

I was working on a collision of giant planets and when I added the Sun, its mass dropped to 58.5 times Jupiter's mass, but its radius stayed roughly the same, therefore defining brown subgiants.
They are hypothetical as far as I know and are supposedly around the size of our star but don't have enough mass for nuclear fusion.

Plus, when I experimented collisions with Jupiter with other planets (including more Jupiters), Jupiter ended up showing a terrestrial appearance despite not having enough mass to behave as a terrestrial of that size.

UY Scuti revised.
Based on measurements from the multimessenger monitoring of supernovae.

The wolf-rayet stars R136a1 and BAT99-98.
R136a1 is revised and BAT99-98 is nearly identical (yet somewhat brighter).

Universe Sandbox ² | Updates / Re: UY Scuti should be fixed, Stephenson 2-18 to be removed until further notice

Furthermore, measurements based on the multimessenger monitoring of supernovae estimated the radius of UY Scuti to be 909 times the Sun's radius, and its effective temperature to be 3,550 K and its luminosity at 124,000 times the Sun's.

Universe Sandbox ² | Updates / An Update needed for the 2024 total solar eclipse simulation

« Last post by Gregory on April 10, 2024, 08:14:21 AM »

The description on the simulation of the total solar eclipse of April 8, 2024 is in need of an update.
It already happened, and the description tells us it hasn't happened yet.
This needs to be fixed in the next update.

Universe Sandbox ² | Support & Bugs / Gas Giants Converting to Terrestrial Giants When Colliding

I was experimenting HAT P-67 b and XO-2 b (the 2 largest known planets) colliding to show the effect of their mass and radius change, and I saw that XO-6 b briefly started showing a terrestrial texture.
This has to be a bug because there's no way gas giants could look rocky when colliding unless they're stripped of their gaseous layers, leaving behind their dense cores.
