Every birthday is one more lap around the Sun.
Enter your birthday and get cards of your journey through space, ready to share: your laps and distance, the planets on the day you were born, your birthday moons, and more. There’s a short film too.
Finding the planets…
Drag to look around. Planet positions are to scale; the planets are drawn larger so you can see them.
What you get
The planets, then and now
Every planet exactly where it was on the day you were born, and exactly where it is today.
Your numbers and laps
Laps around the Sun, distance, days and Moon orbits since you were born, your top speed, Earth’s looping route through space, and badges only your birthday earns.
Planet birthdays and moons
Your age on every planet, your next planet birthday, and the Moon’s phase on every birthday you’ve had.
Your birth-light
Sunlight from the day you were born is still traveling. See which stars it has passed so far.
Your sky and the Sun’s dance
Where every planet was when you were born, your eclipses and zodiac sign as astronomy sees it, and the Sun’s own wobble in your lifetime.
Coming up, and a film
The dates to save next, for your calendar. Plus a short film of every lap since your birthday, to watch or post as a Reel.
What’s real and what’s drawn
- To scale
- Every planet position and every path.
- Drawn larger
- The Sun and planets, so you can see them. At true size they would be invisible specks.
- Measured against nearby stars
- The loops. Against the whole galaxy, moving at about 230 km/s, the same path stretches into an almost straight wave.
- A rendered model
- The Milky Way. Nobody has photographed our galaxy from outside.
