Miller's Planet Time
Equivalent Earth Time
If you spent 1 hour on Miller's Planet, approximately 7 years would pass on Earth using the movie's time-dilation ratio.
What Would Happen While You Were Gone?
These calculations are based on the elapsed Earth time using the Interstellar scenario's 1-hour-to-7-years ratio.
Conversion Basis: 1 Miller's Planet hour = 7 Earth years (from Interstellar movie scenario)
How the Calculation Works
The Core Concept: In the movie Interstellar's scenario, 1 hour on Miller's Planet ≈ 7 Earth years. This extreme time dilation occurs due to the planet's proximity to the black hole Gargantua.
Conversion Basis: This calculator uses the time-dilation scenario from the 2014 film Interstellar, where gravitational time dilation near a black hole creates this dramatic ratio between Miller's Planet time and Earth time.
The Formula: The calculator applies this relationship to all time conversions:
- Miller → Earth: Multiply Miller's Planet time by 7 years per Miller hour
- Earth → Miller: Divide Earth time by 7 to get Miller's Planet equivalent
Derived Conversions: From the base 1-hour = 7-years ratio:
- 1 Miller minute ≈ 42.6 Earth days (1 hour ÷ 60)
- 1 Miller day = 168 Earth years
- 1 Miller year = 61,320 Earth years
- 1 Earth year = 0.143 Miller hours (≈ 8.6 Miller minutes)
Important: This is a simplified, fictional scenario for entertainment and science education. Real gravitational time dilation near black holes would depend on precise distance from the event horizon and the black hole's mass.

How to Use This Calculator
What is Miller's Planet? In Interstellar, Miller's Planet is a fictional water world orbiting Gargantua, a supermassive black hole. Due to its extreme proximity to the black hole, the planet experiences severe gravitational time dilation—a consequence of Einstein's general relativity where time passes at different rates depending on gravitational field strength.
How Does Gravitational Time Dilation Work? Einstein's theory of general relativity shows that massive objects curve spacetime. Stronger gravitational fields cause time to move more slowly. Near a black hole's event horizon, this effect becomes extreme: clocks run slower, and observers age more slowly relative to those in weaker gravitational fields far from the black hole.
Why Is Time Slower Near Gargantua? Miller's Planet orbits so close to Gargantua that it experiences intense gravitational effects. The planet is caught in the black hole's gravitational well, creating extreme time dilation where one hour on the surface corresponds to seven years in Earth's weaker gravitational environment. This drives the plot: astronauts must balance limited time on Miller's Planet against massive time loss relative to Earth.
How Does This Calculator Work? This tool explores the 1-hour-to-7-years conversion in both directions. Enter Miller's Planet time to see how much Earth time passes, or enter Earth time to see how much Miller's Planet time elapses. The "What Would Happen While You Were Gone?" section provides context by showing aging, birthdays, and years that pass.
Is Time Dilation Actually Possible? Yes. Time dilation is a real phenomenon proven by relativity theory and confirmed through experiments. GPS satellites must account for relativistic time dilation. However, the Interstellar scenario is significantly simplified. Real black holes would produce even more extreme time dilation depending on distance from the event horizon. The 1:7 ratio in the movie is science-inspired fiction rather than a precise calculation.
How Does Real Relativity Differ? In reality, time dilation near a black hole depends on the Schwarzschild metric and your precise distance from the event horizon. The effect is continuous and gets more extreme the closer you approach. Interstellar simplified this complex physics into a fixed ratio for storytelling, making it easier to understand while remaining grounded in real relativistic concepts.
Frequently Asked Questions
How long is 1 minute on Miller's Planet in Earth time?
1 minute on Miller's Planet equals approximately 42.6 Earth days. Calculation: (1 minute ÷ 60 minutes) × 7 years ≈ 0.117 Earth years.
How long is 1 hour on Miller's Planet in Earth time?
1 hour on Miller's Planet equals 7 Earth years. This is the core ratio used in Interstellar's depiction of gravitational time dilation near Gargantua.
How long is 1 day on Miller's Planet in Earth time?
1 day (24 hours) on Miller's Planet equals 168 Earth years. A single full day on the planet's surface would mean 168 years passing on Earth.
How much Miller's Planet time equals 1 Earth year?
Approximately 0.143 Miller hours (about 8.6 Miller minutes) equals 1 Earth year. Calculation: 1 Earth year ÷ 7 years per Miller hour ≈ 0.143 Miller hours.
Why does time move differently near Gargantua?
According to Einstein's general relativity, massive objects curve spacetime. Strong gravitational fields slow time. Near Gargantua (a supermassive black hole), gravity is so intense that time literally moves slower compared to areas with weaker gravity. The closer to the event horizon, the more extreme the effect.
Is the 1-hour-to-7-years ratio scientifically accurate?
Time dilation is real physics, but the Interstellar ratio is simplified fiction. Real black holes produce different ratios depending on distance from the event horizon and the black hole's mass. The movie uses a fixed ratio for narrative simplicity while remaining grounded in relativity principles.
Is Miller's Planet real?
No, Miller's Planet is fictional. It was created for Interstellar to explore time dilation and gravitational effects near a black hole. However, the underlying physics of gravitational time dilation is based on Einstein's theory of general relativity, which is real and experimentally proven.
How long were Cooper and Brand on Miller's Planet in the movie?
Cooper and Brand spent approximately 3 hours on Miller's Planet. During those 3 hours for them, approximately 21 years passed on Earth based on the 7-years-per-hour ratio. When they returned, even more time had passed due to additional relativistic effects during their journey.
