What is "calculate your weight on the sun"?
To calculate your weight on the sun is to determine the force exerted on your body's mass by the massive gravitational field of the Sun. Unlike mass, which remains constant throughout the universe, weight is a variable force that depends entirely on the local acceleration due to gravity.
This calculation is popular among physics students, astronomers, and sci-fi enthusiasts who want to understand the sheer scale of our star. The Sun contains approximately 99.86% of the total mass of the solar system, resulting in a surface gravity that is nearly 28 times stronger than Earth's.
While it is impossible to actually stand on the Sun due to its extreme heat and gaseous nature, understanding how to calculate your weight on the sun provides a powerful perspective on the fundamental forces governing our solar system. It illustrates the drastic difference between terrestrial environments and stellar bodies.
Calculate Your Weight on the Sun Formula and Mathematical Explanation
The mathematics required to calculate your weight on the sun relies on Newton's Law of Universal Gravitation. The formula compares the surface gravity of the Earth to that of the Sun.
Where the ratio (Gravitysun / Gravityearth) represents the gravitational multiplier.

Because 274.0 / 9.807 ≈ 27.94, you can roughly estimate that you would weigh about 28 times heavier on the Sun than you do on Earth.
Practical Examples (Real-World Use Cases)
To better understand the implications when you calculate your weight on the sun, let's look at two detailed examples using realistic numbers.
Example 1: An Average Adult
Input Weight: 180 lbs (approx. 81.6 kg)
Calculation: 180 × 27.94
Result: 5,029 lbs
Interpretation: An average adult standing on the "surface" of the Sun would feel as if they were carrying a large SUV on their back. The structural integrity of the human skeleton would fail instantly under this crushing weight.
Example 2: The Mars Rover (Perseverance)
Input Weight: 1,025 kg (approx. 2,260 lbs)
Calculation: 1,025 × 27.94
Result: 28,638 kg
Interpretation: Even a robustly engineered robotic rover designed for space travel would be flattened. This highlights why missions to the Sun (like the Parker Solar Probe) orbit the star rather than attempting to land.

Key Factors That Affect Solar Weight Calculations
When you calculate your weight on the sun, several physical and financial-analogous factors come into play. Understanding these ensures accuracy in your astrophysical models.
Photosphere Definition: The Sun is gas, so it has no solid surface. The calculations use the surface gravity at the photosphere (the visible surface).
Mass Constancy: Your mass does not change. If you are 80kg on Earth, you are 80kg on the Sun. Only the force (weight) changes.
Centrifugal Force: The Sun rotates. At its equator, the centrifugal force might slightly reduce effective weight, though the effect is negligible compared to the massive gravity.
Distance from Center: Gravity follows the inverse-square law. Being slightly higher in the Sun's atmosphere would reduce the calculated weight.
Variable Gravity: Unlike Earth, the Sun's density is not uniform, which can create micro-variations in gravitational pull depending on depth.
Instrumentation Precision: In scientific contexts, the precision of the value used for Earth's gravity (9.8 vs 9.81 vs 9.807) can alter the final result by several pounds.
Frequently Asked Questions (FAQ)
Would I be crushed if I stood on the Sun?
Yes. When you calculate your weight on the sun, you see that a human would weigh over 4,000 lbs. The human skeleton cannot support this load, and you would be crushed instantly by your own weight, even ignoring the extreme heat.
Does my mass change on the Sun?
No. Mass is the amount of matter in your body. Weight is the force of gravity acting on that mass. Your mass remains exactly the same on Earth, the Moon, and the Sun.
Why is the Sun's gravity so strong?
Gravity is directly proportional to mass. The Sun comprises 99.8% of the solar system's mass, creating a gravitational well deep enough to keep all planets in orbit.
How does this compare to Jupiter?
Jupiter is the largest planet, but its gravity is only about 2.4 times that of Earth. The Sun's gravity is over 10 times stronger than Jupiter's.
Is the calculation the same for objects like cars or buildings?
Yes. The ratio of ~27.9 applies to any object. A 2-ton car would effectively weigh nearly 56 tons on the Sun.
Can we land on the Sun?
No. The Sun has no solid surface to land on, and the temperatures exceed 5,500°C (9,900°F). Probes only orbit or pass through the outer atmosphere.
What is the exact gravity of the Sun used here?
We use the standard astrophysical value of 274.0 m/s², which is the equatorial surface gravity.
Why calculate your weight on the sun if we can't go there?
It is a fundamental exercise in comparative planetology. It helps visualize the magnitude of forces in our universe that are otherwise abstract numbers.
