The current “planet alignment” at the end of February 2026 is a short‑lived evening show: the tightest lineup is really just an hour or two, but the broader parade lasts several days on either side of 28 February.

How long are the planets “aligned”?

When people ask “how long will the planets be aligned?” , they usually mean: For how many days can I see several planets strung out in a line in the sky? For the late‑February 2026 event:

  • The main date is 28 February 2026, when six planets are above the horizon after sunset: Mercury, Venus, Saturn, Jupiter, Uranus, and Neptune.
  • The visibility window stretches from late February into early March , depending on where you live.
  • Around that main date, the planets trace an arc along the ecliptic each evening, so you can catch a similar line‑up for several nights before and after 28 February.

In other words, the “alignment” as a trend lasts days, but the night when it looks most compact is centered on 28 February.

How long each night?

On any given night, the alignment at dusk is brief, mainly because Mercury and Venus dive below the horizon quickly.

  • The tight parade ends soon after Mercury and Venus set , which is not long after sunset.
  • You typically get about an hour or so after sunset to see all six above the horizon, with Mercury being the limiting factor.
  • After that:
    • Saturn hangs around roughly an hour longer.
* Uranus can remain visible until around **midnight**.

* Jupiter lasts the longest, often **until just before sunrise**.

So the spectacular “all‑together” view is a short early‑evening window, but some of the same planets remain up for many hours.

What astronomers really mean by “alignment”

Astronomers use “planetary alignment” or “planet parade” in a looser, visual sense:

  • It means several planets appear in the same part of the sky, roughly along a line (the ecliptic) , not that they form a perfect straight line in space.
  • Because their orbits are slow, these line‑ups change gradually , which is why you can see a similar pattern over multiple nights rather than a single instant.
  • True, perfectly straight geometric line‑ups of all planets are extraordinarily rare and not what’s happening here.

This is why news and forums often call it a “planet parade” instead of a one‑moment cosmic event.

Other upcoming alignments (2026 and beyond)

If you are thinking more broadly than just this week and wondering how long this kind of trend lasts into the future , there are several more notable line‑ups on the way:

  • 2026 events include:
    • 28 February 2026: big evening alignment with six planets.
* 18 April, 12 June, 12 August, 14 November 2026: smaller or different‑time‑of‑day alignments with 3–6 planets.
  • Looking a bit further:
    • 2 July 2027: another large morning alignment of five planets.
  • Over decades, there are rarer, more compact multi‑planet parades, but they are still spread over days rather than minutes , in visual terms.

So “how long will the planets be aligned?” in a broader sense: there’s a cluster of noticeable alignments through 2026–2027 , but the photogenic, six‑planet dusk parade we’re talking about is mainly a late‑February to early‑March 2026 phenomenon.

Forum‑style quick scoop

Many posts make it sound like the planets will suddenly snap into a perfect line and then it’s over in a heartbeat.
In reality, you get several evenings to enjoy a curved line of planets along the sunset sky, with the tightest version around 28 February 2026 and a short 1‑hour window each night when they’re all up together.

TL;DR:

  • “Aligned” as a newsworthy event: late February to early March 2026.
  • “Aligned” on any one night: roughly the first hour after sunset , until Mercury and Venus set.

Meta description (SEO‑style):
Wondering how long will the planets be aligned in 2026? The six‑planet “parade” peaks on 28 February but remains visible for several evenings, with about an hour each night to see all six together.
