Basic Planetary Data

[Eddie W. Shore]

HP Prime Basic Planetary Data

The program PLANETS and PLANETDATA retrieve data about our solar system planets, including our dwarf planet, Pluto.

PLANETS presents you with a choose menu which will present a screen of all the data for a planet.

PLANETDATA allows you to retrieve a specific item for a planet. PLANETDATA has two arguments: n for the planet, k for the data point. This is useful if you want to pull out a specific data point for calculations.

Table for PLANETDATA(n, k):

Code:


Value    Planet (n)    Data Point (k)
1    Mercury    Name of the Planet
2    Venus      Radius (km)
3    Earth     Mass (kg)
4    Mars      Gravity (m/s^2)
5    Jupiter    Density (g/cm^3)
6    Saturn    Axial tilt (°)
7    Uranus    Period (days)
8    Neptune    Number of Moons
9    Pluto (dwarf planet)

Example:

The gravity on Mars. PLANETDATA(4,4) returns 3.71 m/s^2.

The diameter of Saturn. PLANETDAT(6,2) returns 58,232 km.
