Linus

Lore & Background

In the sprawling Kerbol system, the major planets and their moons carry the weight of Kerbal history—Mun's first boots, Duna's red dust, Laythe's oceans. Linus, by contrast, exists in the margins. It is the kind of body a Kerbal might notice only as a faint smudge on a navball during a long transfer window, a gravitational whisper rather than a destination.

Fan communities have adopted Linus as a symbol of the KSP universe's quiet vastness: the reminder that beyond the carefully charted orbits of the seven major planets, the system stretches into regions of scattered debris, faint light, and silence. In fan fiction, Linus often serves as a lonely waypoint, a place where a stranded Kerbal drifts in a decaying orbit, or where a forgotten probe finally tumbles into a slow, silent death.

Because no official KSP narrative, patch note, or character bio has anchored Linus to a specific event, its lore remains deliberately open—a blank canvas on which the community projects its own small, melancholy stories about exploration, isolation, and the sheer scale of the Kerbol system.

In Their Own Story

The navball flickered. Somewhere past the last bright ring of Jool, past the slow waltz of its moons, the little green dot had stopped meaning anything. No orbit to intercept. No body to rendezvous with. Just the faint, almost imagined pull of something small and cold dragging the craft's velocity a fraction of a degree off course.

K. Kerman pressed her thumb against the throttle and whispered, "Linus. You're real, aren't you?" The answer, if it came, was only the hum of the RCS thrusters and the slow rotation of the stars beyond the viewport. She set the navball to the smudge, watched the transfer window open like a slow exhale, and let the ship fall the long, quiet way toward a name she'd read in a forum thread three years ago and never forgotten.

It would take eleven days to arrive. She had enough coffee for nine.

Reader's Guide

Linus is best understood as a deep-system waypoint rather than a destination. Its radius, surface gravity, and orbital period are not fixed in any widely cited canon source, so treat any specific figures with caution. What is consistent across fan references is its small size, its lack of a meaningful atmosphere, and its position in the outer Kerbol system where solar illumination is thin and thermal management becomes a constant concern.

As a mission target, Linus is a natural fit for a long-range probe or a low-delta transfer exercise: the challenge is not landing but simply reaching it. The orbital mechanics favour a Hohmann-style transfer from a Jool-orbiting body, with a small correction burn near periapsis to match the faint gravitational influence. Expect a long coast phase and very little in the way of surface features to photograph—mostly regolith, shadow, and the distant glow of the Sun reduced to a very bright star.

The notorious trap for new pilots is overestimating Linus's gravity well. Because the body is so small, a miscalibrated insertion burn can send a craft sailing past it with barely a velocity change, leaving the Kerbal to chase a ghost across the system. Plan your Δv budget generously, and remember: out here, the silence is the loudest thing you'll hear.

Did You Know?

• Linus does not appear in the standard KSP planet/moon list (Kerbin, Moho, Eve, Duna, Vall, Jool and their moons), which is why it occupies a unique 'fan-lore' space in the community.
• In KSP, the outer system beyond Jool is largely uncharted in official missions, making any small body in that region a natural subject for speculative fan narratives.
• The name 'Linus' in KSP community usage often evokes the broader Kerbal tradition of naming things after small, overlooked details—much like the game's own habit of naming moons after mundane objects (Mun, Minmus, Bop, P
• Because no canonical landing or crewed mission to Linus is recorded in base-game lore, any 'first landing' claim in fan content is, by definition, a work of fiction.
