An estimated 3000 metric tons of helium are generated per year throughout the lithosphere of the Earth by radioactive decay. Industry uses about 32 million kg per year, which is 10 times the amount the Earth can produce. Eventually we will use up more than the Earth produces and let it all escape into space.

a year
Neptune's year, or orbital period, is approximately 60,190 Earth days, which is equivalent to about 164.8 Earth years. This is due to Neptune's far distance from the Sun, resulting in a much longer orbital period compared to Earth's 365-day year.
Helium was discovered in 1868 by French astronomer Jules Janssen during a solar eclipse while observing the sun's spectrum.
A Neptunian year is much longer than a year on Earth because Neptune is significantly farther from the Sun, resulting in a longer orbital path. It takes Neptune about 165 Earth years to complete one orbit around the Sun, due to its greater distance and slower orbital speed. In contrast, Earth orbits the Sun in just one year, as it is much closer and moves faster in its orbit. This vast difference in distance and orbital dynamics accounts for the length of a year on each planet.
hi, helium was first observed in the year 1868 by Pierre Janssen and Norman Lockyer. On March 26, 1895, Scottish chemist Sir William Ramsay isolated helium on Earth.
Helium was discovered in 1895 by William Ramsay.
Helium was discovered in 1868 as a new spectral line in light from the sun by French astronomer Jules Janssen during a total solar eclipse in Guntur, India. In the same year, Norman Lockyer, an English Astronomer concluded that the new spectral line was caused by an element in the Sun unknown on Earth and named it Helium. In 1882, Italian physicist Luigi Palmieri detected helium on Earth for the first time. March 26, 1895 Sir William Ramsay, a Scottish chemist, isolated helium on Earth.
