Mars Dust Storm Seasons 3D Explorer vs Earth Perihelion and Aphelion 3D Explorer
freetoolonline.com editorial teamBoth pages teach a real orbital figure in one page load - 0 MB installed, USD 0, no account. The Mars Dust Storm Seasons 3D Explorer scrubs Mars's visibly egg-shaped orbit to show WHEN its dust-storm season happens and WHAT a global storm does to a rover; the Earth Perihelion and Aphelion 3D Explorer scrubs Earth's much rounder orbit to show the small, counter-intuitive distance swing behind Earth's seasons.
The numbers side by side
| Aspect | Mars Dust Storm Seasons Explorer | Earth Perihelion and Aphelion Explorer |
|---|---|---|
| Install size | 0 MB - runs in the browser | 0 MB - runs in the browser |
| Price | USD 0 | USD 0 |
| Orbital eccentricity | 0.0935 | 0.0167 |
| Key figure | 2018 storm tau near Opportunity: about 10.8 | Extra solar flux at perihelion: about 7% more than at aphelion |
| What it varies | Day-of-Mars-year slider (0-687), global-storm toggle | Day-of-year slider (0-365), perihelion/aphelion jump buttons |
| What it answers | When and why Mars gets a dust-storm season | How much Earth's Sun-distance actually varies over a year |
Where the Mars Dust Storm Seasons Explorer wins
The Mars Dust Storm Seasons Explorer wins when the question is about WEATHER and MISSION RISK - it is the only page on the site that connects an orbit's shape to a real dust-storm season and a real rover mission ending.
Where the Earth Perihelion and Aphelion Explorer wins
The Earth Perihelion and Aphelion Explorer wins when the question is about a NEAR-CIRCULAR orbit - it shows why "closer to the Sun" does not mean "hotter" for Earth, a distinction Mars's far more eccentric orbit does not illustrate the same way.
A reasonable rule
As a reasonable rule, use the Mars Dust Storm Seasons Explorer first to see how an eccentric orbit drives a real weather season, then use the Earth Perihelion and Aphelion Explorer to see the same orbit-ellipse scene applied to a much rounder orbit with no dust-storm season at all.

Why trust these tools
- Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
