    This was a Standard Weight tank and was painted white Debris from Salyut 7, which landed in Argentina in 1991. This is a list of artificial objects reentering Earth's atmosphere by mass (see space debris). Such objects are often completely destroyed by reentry heating, but large enough objects or components can survive.

    en.wikipedia.org/wiki/Synthetic_element

    [5] [6] Synthetic elements now present on Earth are the product of atomic bombs or experiments that involve nuclear reactors or particle accelerators, via nuclear fusion or neutron absorption. [7] Atomic mass for natural elements is based on weighted average abundance of natural isotopes in Earth's crust and atmosphere. For synthetic elements ...

    Below is a list of artificial objects currently in heliocentric orbit, but not intended to orbit or land on any planetary or satellite body.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.

    Escape velocity from the sun without the influence of Earth is 42.1 km/s. In order to reach this speed, it is highly advantageous to use as a boost the orbital speed of the Earth around the Sun, which is 29.78 km/s. By later passing near a planet, a probe can gain extra speed from a gravity assist.
