The absolutely best explanation of space dust from astronaut Chris Hadfield. He is my forever hero just for this clip.

Mega-Maid was originally designed to vacuum space-dust but the Spaceballs had other ideas.

The real MVP!! As soon as I read the headline, I had to wonder how much Earth loses each year. Net gain? Net loss?

According to Universe Today:

"The Earth’s mass is 5.9736 x 1024 kg. That’s a big number, so let’s write it out in full: 5,973,600,000,000,000,000,000,000 kg. You could also say the Earth’s mass is 5.9 sextillion tonnes."

So this is a tiny tiny fraction of the total.

Net loss. ~100,000 tons lost (atmospheric escape), 45,000 tons gained.

The Earth gains 500k new humans, and looses 300k, for a net gain of 200k Humans every 24hours, Is the Earth getting Heavier Every Moment?, in basically all the same geographic regions?_Including moving more concrete to those places, concentrating the effect, also, more humans,buildings vehicles and cargo all congeal to that same space! Think that might effect fault lines?! Just a thought? 🌐

No. Earth does not gain mass when humans increase in number.

I was wondering about the composition of this dust, but apart from

>The ablated metallic vapours oxidize and the resulting metal oxides, hydroxides and carbonates condense into nm-sized particles termed meteoric smoke (Plane et al., 2015).

I couldn't really find anything more specific, but I do concede that I just scrolled through it. Is there anything I missed there?

While that's a lot of dust, I think it's a net loss annually considering how much of the atmosphere we lose to space every day.

Cetun t1_issxhgv wrote

On the scale of the entire Earth that actually doesn't seem like very much dust at all especially considering that's spread out throughout the entire world and the amount of space the Earth flies through. Considering every year over 6,000 meteors reach the ground, and the inner solar system is probably still filled with dust from extra planetary collisions and solar winds, you would think that number would be higher.

FreneticPlatypus t1_isszl6m wrote

Honestly for me, masses and distances and numbers that big are beyond comprehension. The article could give any number and I probably wouldn’t argue it.

Fallacy_Spotted t1_isqvey1 wrote

Several hundred tons < 5200 tons of dust. While the Earth does lose a lot of mass from solar erosion it will still gain more from dust each year.

PA2SK t1_isr46dn wrote

The earth loses around 90 tons of atmosphere per day. That's about 32,850 tons per year. Overall the earth is shrinking.

Several hundred tons (of oxygen) a day > 5200 tons of dust each year

A_Vandalay t1_isrb7u5 wrote

Most of the gas lost to space is hydrogen and helium. Due to its lower molar mass it is much easier for these molecules to reach escape velocity.

I have... so much trouble reading this since it's just a mess of punctuation marks and other grammar issues - you don't have to write perfectly, but at least put some effort into it.

> How is 1.2 Million pounds a day per 6pound average birth, in gains, 'to simplify it' via more birth rates than loses, not a gain state?

When a baby is born, do you believe that the mass just comes into existence? The Earth loses significantly more mass due to atmospheric escape than it gains via dust and meteorites. It gains significant energy from the Sun via sunlight, which can be bound into states (via photosynthesis, for instance) which does have a notable effect on things, though. However, most of the matter even in a tree is derived basically from the carbon in the atmosphere.

>A total of 1280 unmelted micrometeorites (uMMs) and 808 cosmic spherules (CSs) with diameters ranging from 30 to 350 μm were identified. Within that size range, we measured mass fluxes of 3.0 μg.m−2.yr−1 for uMMs and 5.6 μg.m−2.yr−1 for CSs. Extrapolated to the global flux of particles in the 12-700 μm diameter range, the mass flux of dust at Earth's surface is 5200 tons.yr−1 ( 1600 and 3600 tons.yr−1 of uMMs and CSs, respectively).
