Inner Solar System at the moment
This page is currently under active development.
The page may not function correctly, and if that is the case, please visit later.
This page shows the current positions of the planets and a few other objects in Inner Solar System.

- The relative sizes of planets are accurate e.g. Earth is slightly bigger than Venus and almost twice the size of Mars.
- However, Sun, because it is very large comparing to the planets, is shown 10x smaller than the planets i.e. Sun is actually approx. 110 times bigger than Earth, but it is shown as approx. 11x bigger.
- The spheres showing objects other than the sun and the planets such as asteroids, comets or spacecrafts are solely to show their actual location, they do not represent their size.
- The positions of the planets and other objects (thus also the distances among them) are actual and accurate relative to each other and to Sun. Up-to-date positions are shown everytime the page is requested (no auto-refresh).
- However, the relative distances are shown much smaller than the relative sizes (e.g. the size of Earth is shown much bigger than its distance to Sun), because, in reality, the distance among planets are huge (there is a vast space among them).
- Moon is not shown for the same reason, because it is too close to earth in this scale.
- The planet orbits shown are equal amount of past and equal amount of future e.g. the orbit of Earth is past 182 days and future 183 days.
- The axial tilt on orbital plane of the planets are probably correct, however it is very hard to verify this other than Earth.
- The planets do not axially rotate (no day and night), so how they look is random (but axial tilt is correct).
- The camera is positioned 50M km further from Earth to Mars.
- The camera (rotation) animation is 0.01 degree per frame. Visually the rotation is in the same direction as the planet orbital rotation, counter-clockwise.
- In addition to Mercury, Venus, Earth and Mars, following objects are currently shown:
- The trajectory and the actual position of Parker Solar Probe in purple.
- The trajectory of Parker Space Probe is past 60 days and future 60 days.
