Everything humanity has put in orbit, and everything the sky has taken back, from Sputnik in 1957 to the CelesTrak snapshot of Oct 29, 2026. Every figure is computed live from the same catalog that drives the 3D atlas.

How orbits filled up

Each band is the number of objects in that orbit class at year's end. The whole stack is everything in orbit, so one picture shows both how fast space filled up and which orbits it filled: low orbit dominates, and the recent surge is the megaconstellations.

How constellations filled up

Each band is a named constellation still in orbit at year's end. The Other band is every unique spacecraft and rocket body the atlas does not color as a fleet. The stack is the same total as the chart above, so you can see which fleets filled the sky: until 2019 almost every object was its own mission, and then the broadband constellations arrived.

The mass in orbit

Counting objects treats a quarter-ton broadband satellite and a twenty-ton station module as equals. Weighing them shows where the substance of the space age actually sits. Masses are GCAT dry masses, the weight of the hardware itself without the propellant it carried up, known for 95% of the objects in orbit; the few unknowns count as zero, so these totals are slightly conservative.

Spent upper stages account for 26% of the mass in orbit, a legacy of the decades when stages stayed up after delivery. Payloads have outweighed them every year since 1997, and the balance keeps shifting the right way: modern upper stages deorbit themselves, so since 2015 the satellite mass in orbit has grown about 8 tons for every ton added in rocket stages.Source: CelesTrak SATCAT; masses from GCAT (J. McDowell, CC BY 4.0).

Entering and leaving orbit

Bars above the line are objects entering orbit; bars below are objects reentering and burning up. Each bar is split by population, so you can see how much of the traffic is working spacecraft (payloads and rocket bodies) versus tracked debris. One shared scale top and bottom keeps the heights honest.

Launches now run into the thousands per year as constellations deploy in batches. Debris creation shows up as sharp spikes at the events that made it: the 2007 and 2009 collisions and anti-satellite tests. Reentries rise and fall with the 11-year solar cycle, which puffs up the upper atmosphere and pulls low orbits down faster.Source: CelesTrak SATCAT. Debris creation dates use the documented breakup dates of the major events; smaller families are dated to their parent launch.

Debris created and cleared

Tracked debris is the fragments too small to be payloads or rocket bodies but big enough to follow from the ground. The good news is in the shape of it: two thirds of everything ever created has already burned up, and modern operators passivate and deorbit to keep it that way.

Zoomed to debris alone, the daily balance tilts the good way: fragments reenter and burn up on most days, while new debris appears only occasionally (a tall bar is a single breakup entering the catalog). Over the whole record, 64% of all tracked debris has already come back down.Source: CelesTrak SATCAT.

Debris does not appear on a smooth yearly curve the way launches do: the public catalog records each fragment under its parent's launch date, not the day it broke apart. So the clouds are best read as events. These are the largest on record, with their documented breakup dates:

What the satellites are for

Every payload in orbit, grouped by the job GCAT records for it. One number explains the shape of the table: the broadband constellations have made communications 74% of everything working up there. Rocket bodies and debris carry no purpose, so this counts payloads only; the newest launches appear as not yet classified until GCAT catches up.

Who is in orbit

Countries and international operators, ranked by active satellites. In orbit counts every intact object they own, retired satellites and spent rocket bodies included, which is why Russia's Soviet-era hardware makes that column so much larger.
