Distance Formula:
From: | To: |
The distance between two points in 3D space is calculated using the Euclidean distance formula, which is an extension of the Pythagorean theorem to three dimensions. This formula gives the straight-line distance between two points in space.
The calculator uses the 3D distance formula:
Where:
Explanation: The formula calculates the straight-line distance between two points in three-dimensional space by taking the square root of the sum of the squares of the differences in each coordinate.
Details: Calculating distances between celestial objects is fundamental in astronomy for understanding stellar relationships, galaxy structures, and cosmic scales. Accurate distance measurements help determine the true brightness of stars and their positions in space.
Tips: Enter the 3D coordinates for both stars in meters. The calculator will compute the straight-line distance between them. All values must be valid numbers.
Q1: What coordinate system is used?
A: The calculator uses a standard Cartesian coordinate system (x, y, z) with all dimensions in meters.
Q2: How accurate is this calculation?
A: The calculation is mathematically precise for the given coordinates, but actual astronomical distances may need to account for relativistic effects over very large distances.
Q3: What units should I use?
A: The calculator uses meters, but you can use any consistent unit as long as all coordinates are in the same unit.
Q4: Can I use this for objects other than stars?
A: Yes, this formula works for calculating the distance between any two points in 3D space.
Q5: How does this relate to astronomical units?
A: For astronomical distances, you may want to convert the result to light-years or parsecs for better context (1 light-year ≈ 9.461×10¹⁵ meters).
