Rida has been puzzled by this question.

"Is the mass of planet earth getting smaller?"

What do you think the answer is? Leave them down in the comments below...

I would have thought Earth is gaining mass due to meteorites landing on Earth.

It is a tradeoff between:
- Incoming atoms from the Solar Wind
- Earth's outer atmosphere, which is being swept away by the solar wind
- Incoming dust and meteorites

We can safely ignore the relatively small amount of mass that humans launch into space.

Hi.

    This question gets discussed fairly often.

This article    https://www.bbc.co.uk/news/magazine-16787636     is a reasonable discussion from 2012,  where the main contributing scientist was Chris Smitch* (of the Naked Scientists).

The conclusion there was ... taking into account the gains and the losses, Dr Smith reckons the Earth is getting about 50,000 tonnes lighter a year,

Best Wishes.

LATE EDITING:     *  Dave Ansell  was also a contributor.  Sorry.  I only scanned the article and may have left out more names than just that one.

Hi everyone;
           A few years ago, Nasa has calculated that the temperature of the Earth is increasing day by day, due to the increase of temperature mass of the Earth is also increase but not in huge amount.

Although it's true that heat increases mass because of E=mc², it's very, very tiny compared to other factors that change the Earth's mass such as atmospheric loss to space and meteorite impacts. Or at least, I'm pretty sure it is. I haven't done the math.
