What you know
Book 1: The Three-Body Problem
- Ch 20The fleet is a square formation of over a thousand artificial star-like ships, each able to reach one-tenth the speed of light.
- Ch 20Its destination is a planet-bearing star about four light-years away, the closest star to the Trisolaran system; the journey will take four or five hundred years.
- Ch 28The Trisolaran Fleet has already set sail for the solar system and will arrive in four hundred and fifty years.
- Ch 30The fleet can reach one-tenth light speed but accelerates in spurts, collecting antimatter fuel with a magnetic funnel, so the trip takes over four hundred years.
- Ch 32The fleet needs 60,000 more hours to be spaceworthy, cruises at one-hundredth light speed, and can decelerate only once.
- Ch 33The fleet is expected to reach Earth in 4.5 million hours; the princeps calls it a funeral procession since humans will be far more advanced.
- Ch 33It launched twenty thousand hours before the meeting, ignorant of its target's distance, and was then redirected toward Earth's star.
Book 2: The Dark Forest
- Ch 2In Year 3 of the Crisis Era the fleet is 4.21 light-years from the Solar System.
- Ch 2The fleet adjusted its deployment to detour in four directions at the Kuiper Belt and encircle the Solar System, to prevent humanity fleeing.
- Ch 2Too small for Hubble II to detect; the public wrongly believes the telescope will be able to see it.
- Ch 3The brush is the wake of about a thousand high-speed ships crossing interstellar dust near the three stars, expanded to twice Jupiter's diameter.
- Ch 5The fleet is at maximum acceleration and launched ten truck-sized probes that will reach the Solar System at least half a century before the fleet.
- Ch 7According to Xiong Wen, the fleet has grown sparse, over half its ships have stopped accelerating, and it won't arrive for over eight hundred years.
- Ch 7One Trisolaran ship never decelerated and is still accelerating, set to reach the Solar System fifty years before the rest of the fleet; humans infer it comes to negotiate.
- Ch 7Humans predict the lone advance ship cannot decelerate enough and would pass through the Solar System in 150 years, possibly dropping a craft with a negotiation delegation.
- Ch 9The Trisolaran fleet cannot stop before the Oort Cloud; changing course would doom it to drift into space, as life support would not last.
- Ch 9The Trisolaran Fleet will begin changing course ten Earth minutes after the exchange; humans will see the heading change in two years.
Book 3: Death's End
- Ch 7The Trisolaran Fleet will arrive in about four hundred years and will be decelerating when it reaches the Oort Cloud.
- Ch 7Wade expects the Trisolarans, knowing the probe's trajectory, to intercept it and capture the human specimen.
- Ch 42The Trisolaran Fleet is the only alien spacecraft humans have any information about.
- Ch 44Sailing ever farther away, weakening the connection between Trisolarans and humanity.
