EARENDIL-1 Passes
Over Toronto
Predicted pass geometry, viewing conditions, and beam footprint data for Toronto when EARENDIL-1 — the first commercial orbital mirror — launches in mid-2026. At 43.7°N, Toronto gets excellent EARENDIL-1 pass geometry — up to 74° elevation.
What to Expect in Toronto
What EARENDIL-1 Will Look Like from Toronto
From Toronto, EARENDIL-1 passes will appear as a fast-moving point of light crossing the sky in approximately 3–4 minutes. At peak brightness it will reach magnitude ~−4 — comparable to Venus at maximum and clearly visible even from the light-polluted city centre. It will be one of the brightest objects in the sky during a pass.
The mirror is steerable — between targeted commercial passes, Reflect Orbital tilts it away from Earth, making it much dimmer or invisible. During an active commercial pass you'll see a sudden brightening as the beam angle locks onto the target region. The pass ends abruptly when the mirror tilts away again.
Unlike a steady satellite, EARENDIL-1 may show subtle brightness variations as the mirror adjusts its aim. Watch for a brief period of maximum brightness near the peak of the pass when the geometry is optimal — this is when the 5km ground footprint is directly beneath the mirror at closest approach.

How bright will EARENDIL-1 appear from Toronto?
At peak overhead passes, EARENDIL-1 is designed to reach magnitude ~−4 — comparable to Venus at maximum brightness and clearly visible from anywhere in Toronto regardless of light pollution. This makes it one of the most conspicuous objects in the sky during a pass. Between commercial illumination passes, Reflect Orbital will tilt the mirror away from Earth, reducing brightness significantly.
How high will EARENDIL-1 appear from Toronto?
At 43.7°N, Toronto gets excellent EARENDIL-1 pass geometry — up to 74° elevation. The CN Tower makes a useful north-south reference when tracking passes across the city. The exact elevation varies pass by pass depending on the orbital geometry. Higher elevation passes give a longer viewing window and brighter appearance as the mirror is closer to the observer.
When is the best time to see it from Toronto?
April–May and August–October. Toronto's winter brings bitter cold but exceptional Arctic air clarity. Summer near solstice has near-perpetual twilight. Spring and autumn are ideal — warm enough to stand outside, dark enough to see faint objects. Near the summer solstice, darkness barely arrives before midnight, so late-spring and early-autumn passes give the best balance of comfort and sky darkness.
Will the beam footprint hit Toronto?
A 5km beam footprint could cover downtown Toronto from the CN Tower to the Distillery District in a single pass. Lake Ontario to the south creates an interesting contrast between lit land and dark water during beam illumination. Whether any specific location falls in the footprint depends on Reflect Orbital's commercial contracts and targeting decisions. The beam is steerable so it can be directed to specific cities or regions for commercial lighting purposes.
Is EARENDIL-1 visible yet?
No — EARENDIL-1 has not launched yet. Reflect Orbital is targeting a mid-2026 launch. There is currently no space mirror in Earth orbit. OrbitalSolar.ai will update with live pass data from the moment orbital elements are published after launch. Check the mission tracker for current launch status.
How does Lake Ontario change the EARENDIL-1 viewing experience?
Lake Ontario — 311km long and 85km wide — provides two unique advantages. First, observers on the Toronto waterfront have an unobstructed flat horizon to the south, allowing them to spot the mirror as it rises earlier and follow it longer than from anywhere inland. Second, if the 5km beam footprint crosses the lake's surface, the reflective water would create a dramatically visible illuminated patch on the water visible from the shore — like a moving circle of moonlight on the lake surface.
How does Toronto's winter give better mirror viewing than summer?
Toronto in winter (December–February) offers conditions that surprise most observers. Cold Arctic air masses bring exceptional atmospheric clarity — limiting magnitudes of 5–6 from suburban locations, comparable to remote dark sky sites in summer. The longer nights (up to 14 hours) mean more twilight windows per evening. The mirror at magnitude −4 is easily visible even through winter haze. Summer brings shorter nights and higher humidity that reduces sky transparency significantly.
What are the best viewing spots in and around Toronto?
Leslie Street Spit on the waterfront gives an excellent unobstructed southern horizon over Lake Ontario. Rouge National Urban Park (eastern edge of Toronto) offers the darkest city-accessible skies with limiting magnitude around 4. For darker conditions, Torrance Barrens Dark Sky Preserve (160km north, Bortle 3–4) is one of Ontario's best dark sky sites — the mirror itself needs no dark sky but the beam footprint effect on ground or water is far more dramatic from here. Algonquin Provincial Park (260km north) reaches Bortle 3.
