A whole 'population' of minimoons may be lurking near Earth, researchers say

The discovery of 2024 PT5, a small, rocky body dubbed a "minimoon" during its discovery last year, hints at a hidden population of lunar fragments traveling near Earth.

a small, rocky body dubbed a "minimoon" during its discovery last year — may have been blown off the moon during a giant impact long ago

Does this mean "For mini-moon", read "asteroid"?

super stoked

I feel like this is evidence the moon eventually erupts from sheer pressure spewing water and debtis out. the debris will be chunks because soil on the moon in frozen beneath the surface I believe

Energy has to come from somewhere.

At its very centre, the Moon has a solid iron core with a temperature of between 1,327°C and 1427°C. This is hot enough to create a surrounding molten liquid iron outer core, but not hot enough to warm the surface. The mantle, which envelops the core, is roughly 1,000 kilometres thick.

There is not enough energy to allow the Moon to "explode", in fact "not hot enough to warm the surface", Frozen chunks have low energy. Give them energy, and they melt. See Latent Heat.

Latent heat can be understood as hidden energy which is supplied or extracted to change the state of a substance without changing its temperature or pressure.

Give heat (energy) to frozen chunks, and they melt without changing temperature or pressure, until they have melted. Thus a lot of energy "disappears" without changing temperature or pressure.

So, to cause "bits" of the Moon to "explode", the energy must come from outside, ergo from impacts.

interesting. There ;is evidence of ;moon volcanoes i am curios how high in the moons gravity ;the eruption would go. the reason I think it will eventually pop is because of the pressure generated by the accumulation of steam under the moons surface. I theorized eruptions were water not magma because the moons core was never reaching the surface with magma rather steam. ;due to my theory of the moon is accumulation not impact born. its a biproduct of a planet

The same latent heat argument applies to ice and water. Give ice chunks a lot of heat and they turn to water at the same temperature, before there can be a temperature increase. There is no pressure increase.
