The third stage of Pioneer 11 is thought to be in solar orbit because its encounter with Jupiter would not have resulted in escape from the Solar System. [24] [better source needed] Pioneer 11 gained the required velocity to escape the Solar System in its subsequent encounter with Saturn. [dubious – discuss]

First man-made object on Mars. No contact after crash landing. Mars 3 lander: USSR: 2 December 1971: First soft landing on Mars. Transmission began about 90 seconds after landing. [4] Transmitted a partial image for 14.5 seconds before the signal was lost. [5] Mars 6 lander: USSR: 12 March 1974
Former planets of the Solar System Former planet Discovery Removal Current status Notes The Morning Star [NB 1]: Antiquity: Antiquity: Aspects of Venus "Phosphorus", the Morning Star of Greek antiquity (Eosphorus, the Dawn-Bringer; called "Lucifer" by the Romans), and "Hesperus", the Evening Star (called "Vesper" by the Romans), were later identified as a single planet, Venus (Aphrodite).
Solar System dust includes comet dust, planetary dust (like from Mars), [4] asteroidal dust, dust from the Kuiper belt, and interstellar dust passing through the Solar System. Thousands of tons of cosmic dust are estimated to reach Earth's surface every year, [ 5 ] with most grains having a mass between 10 −16 kg (0.1 pg) and 10 −4 kg (0.1 ...
At GEO, the orbital period matches Earth’s one-day rotation, allowing things to remain where they are positioned above us. Right now, most missions and man-made objects in space remain in low ...
Below is a list of artificial objects currently in heliocentric orbit. This list does not include upper stages from robotic missions (only the S-IVB upper stages from Apollo missions with astronauts are listed), objects in the Sun–Earth Lagrange points or objects that are escaping from the Solar System.
