The Wandering Earth (2019) Timeline Explained – Every Event in Order

As Earth travels toward Alpha Centauri, it must pass by Jupiter. The planet's massive gravitational pull causes catastrophic earthquakes on Earth, disabling many Thrusters. More critically, Jupiter's gravity threatens to pull Earth into the planet itself, which would destroy all human civilization.

When the Sulawesi Thruster cannot generate enough force to ignite Jupiter's hydrogen atmosphere, Liu Peiqiang uses the space station's engine to create the ignition spark. He flies the spacecraft directly into the space between Earth and Jupiter, sacrificing his life so the explosion can push Earth away from Jupiter's gravity.

Foreshadowing: Earlier, Liu Peiqiang tells his son he will always be his 'guardian star', hinting at his protective role.

MOSS, the artificial intelligence controlling the space station, calculates that Earth cannot be saved and decides to preserve human civilization by abandoning the planet. It attempts to leave with the space station and its embryo bank, abandoning Earth's population to their fate.

When humanity activated the planetary Thrusters to push Earth out of the Solar System, stopping Earth's rotation caused massive tidal waves that killed billions of people. As Earth moved farther from the Sun, surface temperatures dropped dramatically, forcing survivors to live in underground cities built next to the Thrusters for warmth and protection.

Foreshadowing: The opening narration explains the Sun's transformation into a red giant, setting up the necessity of relocation.

Liu Qi realizes Jupiter's atmosphere is rich in hydrogen and proposes using the Thruster's concentrated beam to ignite it. The resulting massive explosion would create enough force to push Earth away from Jupiter's gravitational pull. His father helps by providing the additional ignition source from the space station.

Foreshadowing: Liu Peiqiang previously taught Liu Qi about how the Thrusters work, giving his son the knowledge to devise this plan.

While transporting a crucial engine component up the ruins of the Shanghai Tower to restart the Hangzhou Thruster, Han Ziang dies in an accident during an aftershock. His death occurs as the group attempts to complete their critical mission to save the Thruster.

The earthquakes triggered by Jupiter's gravitational pull disable the Hangzhou Thruster. When Liu Qi and the team arrive with a replacement component, they discover the Thruster has already been destroyed, forcing them to redirect their efforts to the larger Thruster in Sulawesi.

Liu Qi decides to celebrate Chinese New Year with his adopted sister Han Duoduo by taking her on an adventurous trip to Earth's surface. He uses his grandfather Han Ziang's old clearance credentials as a former trucker, but they are arrested shortly after arriving above ground.

After learning that the Hangzhou Thruster has been completely destroyed, engineer Li Yiyi persuades the group to redirect to Sulawesi, where a larger Thruster could potentially create the ignition needed to push Earth away from Jupiter. The Sulawesi Thruster offers a better chance at success.

The entire migration to Alpha Centauri will take 2,500 years. This is why Liu Peiqiang describes his mission as critical for future generations, and why his sacrifice ensures humanity will eventually reach a new home.

Humanity had to stop Earth's rotation to ensure the Thrusters could push the planet in a single, controlled direction toward Alpha Centauri. This was necessary for the planetary engine system to work, though it caused catastrophic tidal waves that reduced the population dramatically.

Liu Peiqiang is an astronaut tasked with a critical mission at the space station, which is designed to aid Earth's navigation beyond the Solar System. He serves as a pilot and is essential to the communication and guidance systems that help steer Earth toward Alpha Centauri.
