Hohmann Transfer Calculator

Property to Calculate:

Semi-major axis of the transfer orbit (A_t):

Radius of initial orbit (r₁):

Radius of final orbit (r₂):

How This Is Calculated

$$ a_t = \frac{r_1 + r_2}{2} $$ where:

a_t = Semi-major axis of the transfer orbit (m)

r₁ = Radius of initial orbit (m)

r₂ = Radius of final orbit (m)

Assumptions

The initial and final orbits are circular.
The transfer occurs between two concentric orbits around the same central body.
The inital and final orbits are coplanaer.
Impulses are instantaneous.
The system is treated as a two-body problem.
