Comet

There are two season in game: Peace Season and Meteor Season. Meteor season begins when you discover the surface. Season counter increases at 0:00 in every cycle (not every 600s). 
    Peace Season lasts 4 cycles, with no meteor.
    Meteor Season lasts 10 cycles, and can be divided into two parts: Break and Meteor Shower.
        Break lasts 300~1200 seconds, without meteor.
        Meteor Shower lasts 100~400 seconds. A new comet will drop every 1~1.5 seconds.

Three kinds of comet

Comets will →damage all the buildings in their route
                    →hit a tile (including undug block and buildings which occupy tile, such as doors, tile)
                    →cause an explosion
                    →divide to debris
                    →create 0~6 new regolith blocks (only when rock comet)

When the comet pass through a building, the building will receive damage, which equals to Building Damage. When the accumulating damage of the building exceed the building's hitpoints, the building will broken.

When the comet hit a tile, an explosion will bring damage to the falling point and its surroundings. The damage is

Damage=Explosion Damage * Explosion Damage Ratio * Multiplier 2.png.c4021cac007748e783a40a0656995f3e.png

In window tile's case, the Multiplier=5; in bunker's case, the Multiplier=0; in the other case, the Multiplier=1.
When the accumulating damage of a tile exceed the element's strength, the tile will broken.

After the explosion, the comet will divide to debris and have a sharp temperature rise. If the comet is rock comet, the comet will create 0~6 regolith blocks.

Meteor Scanner

To keep every Meteor Scanner works in 100% dish quality, the scanner should be 15 tiles away from the closest heavy machinery and have a 31 tile-wide skyline (In the second photo, all the window tiles and the scanner itself should be able to receive solar light).

Detector Network

To compose a Detector Network, the logic output of the detector should be connected to each other.
Each fully dish quality Meteor Scanner can provide 16.67% Detector Network quality, which means 6 fully quality Meteor Scanners can compose a Detector Network with 100% Detector Network quality.
Every percent of Detector Network quality means 2 seconds pre-warning time. A fully quality Detector Network can provide 200 seconds pre-warning time.

Light

3.png.445105f326a2b7cc70bfe28b44fad36c.png

 

Every duplicant has a Light Resistance gauge ( from 0 to 480).
The Light Resistance will restore in Pitch Black (0 lux).
When exposed to strong light (≥71999lux), duplicants feel Intensely Bright (Stess Change: -5%/cycle) but lose Light Resistance slowly (-4/second).
When the gauge is zero(?,need confirm), the duplicant will get sunburn.
The sunburn remain 1.5 cycles. During this time, duplicant won't feel Bright and Cheerful or Intensely Bright and should get reset in Pitch Black.

Solar Light

The lux of Solar Light is based on time. It's 0 at night (21:00~24:00) and reach max 80000 lux at noon (10:30). Solar light will attenuate by environment conditions. 

Light Source

Light Range

Solar panel

Every solar panel receives light from red zone(14 tiles). Every lux can convert to 0.00053W. When the total lux reach 716 981 lux (51 213 on average), the panel can generate the max value, 380W.

Bunker door

Bunker door cost 120W and need 38.2 seconds to close or open. Though Bunker door can defend all the meteor attack, the rock meteor will create a few undug tiles and have to be dig by dups.

Great analysis @R9MX4 . So over a very long period of time, would the mass from the meteorites just accumulate and fill up the top of the map?

The surface will be destroyed by impact, and reshaped by new sand block. I think Klei found a balance between destruction and creation.

What happens when i keep the debris on my bunker tile? Does the bunker tile malfunction? Does it reduce the meteor forecast quality of sensors?

Or is it just blocking the solar light?

It'll fall through the door when it opens. Beyond that it's blocking sunlight.

Some thoughts for a "infinite" solar installation:

Can I keep the area under the doors hot enough that every debris will liquidify and evaporate?

I guess you should keep your door not to be overheated or liquefy at first:D

If you set it up so that comets land in water or another liquid, does it stop the comet from breaking up?

Not sure, I guess can't. But your idea is interesting.

In order for that to work, you'd have to dig the surface away to a point below the background topography.  I wonder how effective that would be in protecting the Panels.  And would the depth of liquid have an effect on light penetration?

So does it make sense to protect solar panels and Meteor detector with Bunker doors, covering all space?

Yes, that's the idea.  Set up the Detectors to watch for Meteors, have them set to close the Bunker Doors before the Meteors fall, and re-open them after it's passed.  Bunker Doors do not take damage from Meteors, so all you have to do is dig off any Sand or Regolith that is deposited.

Currently, no effect.

Based on some rough calculation, I would say it's no benefit to periodic open and close bunker door in meteor season. But we can keep the door always open in peace season and always close in meteor season.

Great work as ONI biology. Maybe add the ecosystem with Shine bug / solar panel.

Did some rough test. One bug provide about 10W. I can't come up with a more power efficient structure. 10W is not a big number for me, so I decided to give up the shine bug solar energy plant.

It would be cool if water stopped the meteors, I would make layer of water a few tiles deep and reap the benefits.... I assume the solar panels can be flooded? I hope they add new types of comets

While its just 10 watts, its still semi free energy, discluding the cost of shinebugs. the panels put out 45 watts of heat when exposed to light, so you could use that to alleviate energy costs of heating stuff up.

A space heater needs 120W engergy to produce 90W of heat.

2 Solar panels with a lamp should be energy positiv (5W energy needed; 16 W produced) and emit 92,5 W of heat ;)

Oh that's so going to get nerfed.

Add and update some information about rock comet.

In a recent update, rock comet is more heavy and can create more regolith blocks. I hope this change can make the surface more stable.

Fun to make but unfortunately it only produces 6.89 watts and costs 8 watts

Despite what they tried to do it looks like shinebugs will work a little.

Just tested this. Turns out water does nothing to meteors. It doesn't slow them down, doesn't cool them off, they pass right through. It also appears to not change the resulting explosion, which since the debris is typically 226.9+ °C it will turn the water to steam.

Spoiler

but what about oil > NG

 

:shock:

do you mean boil oil to ng by heat of meteor?sadly comets are not heat enough. but you could try to use comets to heat steam turbine
