How High Are Starlink Satellites? (2026 Altitude Guide)
Starlink satellites orbit between 330 km and 490 km above Earth, depending on the satellite type. Broadband satellites (V1 and V2) sit at roughly 450โ490 km, while newer direct-to-cell (DTC) satellites orbit lower, at about 330โ370 km. This is a change from Starlink’s original reference altitude of 550 km SpaceX has been actively lowering thousands of satellites throughout 2026 for safety reasons.
If you’ve seen “550 km” quoted elsewhere, that’s the historical figure still listed on some of Starlink’s marketing pages. It’s no longer accurate for most of the active fleet.
What Altitude Do Starlink Satellites Orbit At Right Now?
As of mid-September 2026, Starlink operates two main altitude bands:
Broadband satellites (V1 and V2)
Most of Starlink’s internet-delivering satellites fly at 450โ490 km. This is down from the original 550 km shell, following a fleet-wide lowering that began in January 2026.
Direct-to-cell (DTC) satellites
The satellites powering Starlink’s satellite-to-phone service orbit lower, at roughly 330โ370 km. A small number of older satellites at a 70ยฐ inclination still sit higher, around 570โ580 km, but these are a shrinking minority.
For comparison, a freshly launched batch of Starlink satellites starts much lower often under 300 km before using onboard thrusters to raise themselves into their assigned operational shell over several weeks.
Why Did SpaceX Lower Starlink’s Orbit in 2026?
On January 1, 2026, Michael Nicolls, SpaceX’s VP of Starlink engineering, announced that the company would lower roughly 4,400 satellites from 550 km down to 480 km over the course of the year. Two main reasons drove the decision:
- Collision risk. Fewer other satellites and debris objects occupy the region below 500 km, so condensing Starlink’s orbits reduces the aggregate chance of a collision.
- Faster natural deorbiting. At lower altitudes, atmospheric drag pulls dead satellites down much faster reducing the time a failed satellite spends as space debris from roughly four years to just a couple of months.
The move followed a December 2025 incident in which a Starlink satellite experienced an in-orbit anomaly at 418 km, creating a small amount of debris. That event appears to have accelerated the safety-driven reconfiguration.
By the end of 2026, the FCC-authorized shell structure settles into two bands: 450โ490 km for broadband satellites and 330โ370 km for direct-to-cell and next-generation (V3) satellites.
How Does Starlink’s Altitude Compare to Other Satellites?
| Object | Altitude | Orbit type |
|---|---|---|
| Starlink (broadband) | ~450โ490 km | Low Earth Orbit (LEO) |
| Starlink (direct-to-cell) | ~330โ370 km | Low Earth Orbit (LEO) |
| International Space Station | ~400โ420 km | Low Earth Orbit (LEO) |
| GPS satellites | ~20,200 km | Medium Earth Orbit (MEO) |
| Geostationary TV/weather satellites | ~35,786 km | Geostationary Orbit (GEO) |
Starlink sits in the same general neighborhood as the ISS โ both are firmly within Low Earth Orbit, which runs from about 160 km to 2,000 km. That’s dramatically closer to Earth than GPS satellites or geostationary satellites, which orbit tens of thousands of kilometers away.
Why Does Starlink Fly So Low?
Traditional satellite internet (like older HughesNet or Viasat services) uses geostationary satellites at ~35,786 km. Starlink deliberately chose Low Earth Orbit instead, for three practical reasons:
- Lower latency. Signals travel a much shorter round trip, cutting delay from 600+ milliseconds (geostationary) down to roughly 20โ40 milliseconds.
- Faster deorbiting. LEO satellites burn up in the atmosphere naturally within months to a few years after failure, instead of lingering as debris for decades.
- Smaller, cheaper satellites. Lower orbits don’t require the massive antennas and power systems geostationary satellites need to cover a fixed patch of Earth.
The tradeoff is coverage: a single LEO satellite can only “see” a small patch of ground at a time, which is why Starlink needs thousands of satellites working together instead of the handful a geostationary provider uses.
How Long Does It Take a Starlink Satellite to Orbit Earth?
At an altitude of roughly 450โ550 km, a Starlink satellite completes one full orbit of Earth in about 90 to 95 minutes. That means each individual satellite circles the planet roughly 15โ16 times per day, which is why Starlink needs a large, constantly-moving constellation (over 11,000 satellites as of September 2026) to keep continuous coverage over any given location.
Does Starlink’s Altitude Affect Internet Speed and Latency?
Yes, altitude is the main reason Starlink can offer such low latency compared to older satellite internet providers. Because the satellites are only a few hundred kilometers up rather than tens of thousands, the signal has far less distance to travel. Typical Starlink latency runs 20โ40 ms, compared to 600+ ms for geostationary satellite internet. That’s fast enough for video calls, online gaming, and other real-time applications that older satellite internet historically struggled with.
Lowering the orbit even further in 2026 (from 550 km to 480 km) shaves a small amount of additional latency off the connection, though the collision-avoidance and debris benefits were the primary drivers of that change.
FAQ
How high do Starlink satellites orbit?
Between about 330 km and 490 km, depending on the satellite type. Broadband satellites sit around 450โ490 km; direct-to-cell satellites orbit lower, around 330โ370 km.
Is it true Starlink orbits at 550 km?
That was accurate historically and is still the figure on some older reference pages, but SpaceX has been lowering most of its 550 km satellites to 480 km throughout 2026 for safety reasons.
How does Starlink’s altitude compare to the ISS?
They’re close. The ISS orbits at roughly 400โ420 km, which falls within Starlink’s current altitude range.
Why did SpaceX lower Starlink’s orbit?
To reduce collision risk with other satellites and space debris, and to make sure any failed satellites fall out of orbit and burn up much faster months instead of years.
Does a lower orbit mean Starlink satellites burn up faster?
Yes. Atmospheric drag is stronger closer to Earth, so a dead satellite at 480 km deorbits naturally much sooner than one at 550 km.
How many Starlink satellites are currently in orbit?
As of September 2026, there are over 11,000 Starlink satellites in orbit, making it the largest satellite constellation ever launched.
Does altitude affect Starlink’s internet speed?
Altitude mainly affects latency (delay), not raw download speed. Because Starlink flies much lower than traditional satellite internet, it achieves latency of 20โ40 ms versus 600+ ms for geostationary satellite providers.
