The Death Star’s size compared to Earth is a frequent question. This article will provide a comprehensive comparison of the Death Star with Earth, exploring various aspects such as size, mass, gravity, and more. At COMPARE.EDU.VN, we offer a detailed analysis to help you understand the true scale of this iconic space station, comparing galactic behemoths and astronomical objects. Discover the relative scale, celestial bodies, and astronomical comparisons.
1. What Is The Size Comparison Of The Death Star And Earth?
The Death Star is significantly smaller than Earth. The Death Star has a diameter of approximately 160 kilometers (100 miles), while Earth has a diameter of about 12,742 kilometers (7,918 miles).
To further elaborate, consider these points:
- Diameter Difference: Earth’s diameter is nearly 80 times larger than the Death Star’s. This means you could line up almost 80 Death Stars across the diameter of Earth.
- Volume Difference: The volume of Earth is vastly greater. You could fit approximately 2 million Death Stars inside Earth.
- Visual Perspective: If the Death Star were near Earth, it would appear as a small dot compared to our planet’s immense size.

2. How Does The Death Star’s Size Compare To Earth’s Moon?
The Death Star is smaller than Earth’s Moon. The Death Star’s diameter is about 160 kilometers (100 miles), whereas the Moon’s diameter is approximately 3,475 kilometers (2,160 miles).
- Diameter Ratio: The Moon’s diameter is roughly 22 times larger than that of the Death Star.
- Volume Comparison: The Moon’s volume is significantly larger; you could fit around 220 Death Stars inside the Moon.
- Visual Scale: In the Star Wars universe, Luke Skywalker initially mistakes the Death Star for a small moon, but in reality, even a “small” moon like Earth’s is much larger.
3. What Would It Be Like To Walk On The Death Star Compared To Earth?
Walking on the Death Star would be very different from walking on Earth due to the vast difference in gravity. The Death Star’s gravity is significantly weaker.
- Gravity Differences: Earth’s surface gravity is about 9.8 m/s², while the Death Star’s gravity, even under the most optimistic estimations, would be a tiny fraction of that.
- Weight Perception: If the Death Star were made of solid steel (an unlikely scenario), its surface gravity would be about 2% of Earth’s. This means a person weighing 150 pounds on Earth would weigh only 3 pounds on the Death Star.
- Density Matters: If the Death Star had a density similar to an aircraft carrier (much more realistic), its surface gravity would be only 0.04% of Earth’s. A 150-pound person would weigh a mere ounce.
- Mobility Challenges: Walking would be challenging without assistance like magnetic boots, assuming the Death Star’s material is ferromagnetic.
4. How Does The Mass Of The Death Star Compare To Earth?
The Death Star’s mass is minuscule compared to Earth. Even if the Death Star were made of incredibly dense material, Earth’s mass would dwarf it.
- Earth’s Immense Mass: Earth has a mass of approximately 5.97 × 10^24 kg. Estimating the Death Star’s mass involves several assumptions about its composition.
- Solid Steel Scenario: If the Death Star were a solid ball of steel, its mass would be around 1.7 × 10^15 kg. This is still only about 0.0000000003% of Earth’s mass.
- Realistic Composition: Given the Death Star’s internal structure (including vast empty spaces), its mass would be far less. If we assume it has the same density as an aircraft carrier (200 kg per cubic meter), its mass would be roughly 2.1 × 10^12 kg, an even tinier fraction of Earth’s mass.
- Impact of Gravity: If the Death Star orbited Earth at the Moon’s distance, its gravitational effect on Earth would be negligible. The Moon is approximately 40,000 times more massive than even the most generous estimates for the Death Star.
5. Why Is The Death Star Not Spherical Like Earth Or Other Moons?
The Death Star is not spherical because it is an artificial construct and too small to achieve hydrostatic equilibrium. Natural celestial bodies become spherical due to their own gravity.
- Hydrostatic Equilibrium: This is the balance between an object’s self-gravity and its internal pressure. For objects large enough, gravity pulls everything toward the center, forcing them into a spherical shape.
- Size Threshold: Objects typically need to be at least 200-600 km in diameter to achieve hydrostatic equilibrium, depending on their composition. Ice requires a smaller diameter (200-400 km) than rock (around 600 km) or metal.
- Artificial Structure: The Death Star, with its 160 km diameter, is too small to be spherical naturally. Its shape is maintained by its artificial structure, not gravity.
- Astronomical Anomaly: An experienced astronomer would immediately recognize the Death Star as an artificial object because it does not conform to the natural spherical shape of moons and planets.
6. What Materials Would Be Needed To Build A Death Star?
Building a Death Star would require vast quantities of resources and advanced materials. While the exact materials are fictional, we can speculate based on its design and functionality.

8. What Is The Theoretical Gravity Inside The Death Star?
The Death Star has artificial gravity inside to simulate Earth conditions. However, the natural gravity of the Death Star is extremely weak due to its size and mass.
- Artificial Gravity: In the Star Wars universe, the Death Star uses artificial gravity to allow inhabitants to walk normally inside the station.
- Natural Gravity: Without artificial gravity, the natural gravity on the inner surfaces would be almost non-existent, making it impossible to walk without being anchored.
- Calculations: Assuming the Death Star is a solid sphere of steel, the gravity at its surface would be approximately 0.002 g (where g is Earth’s gravity). If the Death Star has a density similar to an aircraft carrier, the gravity would be about 0.0004 g.
- Practical Implications: This means that without artificial gravity, objects and people inside the Death Star would float around freely.
9. How Does The Superlaser On The Death Star Compare To Real-World Weaponry?
The superlaser on the Death Star is a fictional weapon far beyond the capabilities of any real-world technology.
- Energy Requirements: Destroying a planet requires an immense amount of energy, comparable to the energy output of the Sun over several days.
- Focusing Energy: Focusing such an enormous amount of energy into a coherent beam would be extremely difficult, if not impossible, with current technology.
- Material Limitations: No known material could withstand the energy levels required for a superlaser without vaporizing.

11. Can The Death Star Float In Water?
Surprisingly, the Death Star could float in water if its overall density is less than that of water. This depends on its composition and how much empty space it contains.
- Density Calculation: The density of water is approximately 1,000 kg per cubic meter. If the Death Star’s overall density is less than this, it would float.
- Aircraft Carrier Density: If we assume the Death Star has the same density as an aircraft carrier (200 kg per cubic meter), it would float very high in the water.
- Solid Steel Scenario: If the Death Star were a solid ball of steel (8,000 kg per cubic meter), it would sink rapidly.
- Waterline Effects: If the Death Star floated, its own gravity would cause some interesting effects around the waterline, pulling the water up slightly around the structure.
