There are planets in different sizes and there are stars in different sizes. The Universe is full of wonders.

While our 🌞 sun is a medium-sized 🌟 star compared to others in the Galaxy , it is still significant larger than Earth 🌍 containing enough mass To hold about a million Earths within its volume.

Here's info on an old paper on star spot imaging that I was privileged to have contributed to: Imaging Stellar Surfaces via Matrix Lightcurve Inversion Article December 1996 6 Reads 📷Drish, W. F., Jr📷Robert O. Harmon·📷W. J. Wild·📷Robert Rosner· Matrix lightcurve inversion (MLI) is a method for deducing the appearance of a rapidly-rotating star's surface features (in particular starspots) from its photometric lightcurve. It has the significant advantage over "spot models" that no a priori assumptions are made regarding the number of spots on the surface or their shapes. We present here the results of an extensive set of simulations using synthetic lightcurves generated from artificial surfaces. These have allowed us to test the ability of MLI to reconstruct stellar surfaces under conditions in which the true surface features are known. We demonstrate that MLI represents a viable alternative to other techniques such as spot models and Doppler imaging, and is of particular value when used in conjunction with such techniques.

Our sun may be small, but it's perfect for me :)

You just blew my mind again! I had just got it all stitched back together after the last time.

Comparing late stars that are red giants is not a proper comparison to blue giants. They are just not as massive as the blues

Elon Musk: Everything is solar power. The rest is noise. “The sun is about 99.8% of the mass of the solar system. Jupiter's about 0.1% and everything else is in the remaining 0.1%, and we are much less than 0.1%. So, if you burnt all of the mass of the solar system, then the total energy produced by the sun would still round up to 100%. If you just burnt Earth, the whole planet, and burnt Jupiter, which is very big and quite challenging to burn, turn Jupiter into a thermonuclear reactor, the sun is 99.8% of the mass of the solar system and everything else is in the miscellaneous category. Basically, no matter what you do, total energy produced in our solar system rounds up to 100% from the sun. You could even throw another Jupiter in, so we're going to snag a Jupiter from somewhere else, you could teleport two more Jupiters into our solar system, burn them, and the sun would still round up to 100%. As long as you're at 99.6%, you're still rounding up to 100%. Maybe that gives some perspective of why solar is really the thing that matters. And, as soon as you start thinking about things at a grander scale, like Kardashev Scale 2 civilizations, it becomes very, very obvious. I'm not saying anything that's new, by the way. Anyone who studies physics has known this for a very long time. In fact, Kardashev, a Russian physicist who came up with this idea, I think, in the 1960s, just as a way to classify civilizations, where Kardashev Scale 1 would be, you've harnessed most of the energy of the planet, Kardashev Scale 2, you've harnessed most of the energy of your sun, Kardashev 3, you've harnessed most of the energy of a galaxy. Now we're only about 1% or a few percent of Kardashev Scale 1 right now, optimistically. But as soon as you go to Kardashev Scale 2, where you're talking about the power of the sun, then you're really just saying everything is solar power and the rest is in the noise. Like, the sun produces about a billion times, or call it well over a billion times more energy than everything on Earth combined.” All-In Podcast, October 31, 2025

Earth Could Survive the Sun's Death: New Models Offer Hope 🟠 Our planet has a chance of surviving the Sun's transformation into a red giant and avoiding total destruction in its thermonuclear inferno. Earth's ultimate fate will be determined by a delicate balance between the gravitational pull of the swelling star and its loss of mass; as the star loses mass, its gravitational grip will weaken, allowing the planet to drift to a safer orbit. Astronomers from KU Leuven (Belgium) have revised predictions regarding the future of the Solar System. They conducted gravitational simulations that accounted for the internal structure of aging stars, and their findings were published in the journal *Astronomy & Astrophysics*. In approximately five billion years, the Sun will exhaust the hydrogen fuel in its core, causing it to expand hundreds of times in size and transform into a massive red giant. At that point, a "tug-of-war" will begin within the Solar System, the outcome of which will decide Earth's fate. On one hand, the star's massive expansion will generate powerful tidal effects that act to slow Earth down and drag it inward. On the other hand, the star will actively shed its outer layers into space via powerful stellar winds. As it loses mass, the Sun will become lighter and its gravitational grip will weaken, enabling Earth to migrate further out into the Solar System. Updated calculations indicate that the effect of the Sun's mass loss could counteract tidal drag; in this scenario, our planet would have time to shift to a more distant orbit lying just beyond the radius of the expanded star. To validate their theoretical calculations, the scientists turned to actual observations of the dying giant star L2 Puppis, located 200 light-years away. In the past, it closely resembled the Sun, but now it is rapidly losing mass and is surrounded by a dust disk in which a large planet orbits. The fact that this world survived gives scientists strong grounds to hope that Earth might also be saved. However, there is no cause for optimism regarding our own system's neighbors: computer simulations indicate that Mercury and Venus will inevitably be completely consumed by the flames of the dying star. The launch of the PLATO space telescope will help settle the debate about our planet's future once and for all. It is scheduled to enter orbit next year to search for exop всяlanets around aging stars. 🌙
