Since the Sun is losing mass, can a planet's orbit change be measured?

AI Thread Summary
The Sun loses approximately 4 million tons of mass each second through nuclear fusion, which theoretically could cause planets to gradually spiral outward due to the decreasing gravitational pull. However, this mass loss over 4.5 billion years equates to an increase in Earth's orbit of only about 7,000 miles, a negligible change compared to its current distance of 93 million miles. Additionally, the Sun gains a minimal amount of mass from interstellar debris, which does not significantly offset the losses from fusion. Tidal drag from the Sun also has a minor impact on Earth's orbit. Overall, the effects of the Sun's mass loss on planetary orbits are insignificant and not measurable with current instruments.

Since the Sun is changing 4M tons of matter into energy every second and that energy eventually makes its way to the surface and is emitted as an outbound sphere of EM radiation, then the planets' orbits would change over time due to the less massive Sun at the solar system's core. It would seem that there would be a slow outward spiral of each planet. But is this not perceptible by our instruments? Are other factors countering this effect? Does the Sun gain enough mass from interstellar debris that its gravity sucks into make up for the difference in matter-energy change due to the thermonuclear processes at its heart?

Solar mass loss due to hydrogen fusion amounts to about an Earth mass over the past 4.5 billion years. Theoretically, this would cause an increase in Earth orbit of about 7000 miles - as compared to the ~93 million miles we currently enjoy. The effect is obviously insignificant. The sun accretes only a tiny fraction of mass compared to fusion losses so that effect can be essentially ignored. Earth orbit is also affected by tidal drag from the sun. That effect is also relatively miniscule.
 
Thank you for the response.
 
Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
3I/ATLAS, also known as C/2025 N1 (ATLAS) and formerly designated as A11pl3Z, is an iinterstellar comet. It was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) station at Río Hurtado, Chile on 1 July 2025. Note: it was mentioned (as A11pl3Z) by DaveE in a new member's introductory thread. https://www.physicsforums.com/threads/brian-cox-lead-me-here.1081670/post-7274146 https://earthsky.org/space/new-interstellar-object-candidate-heading-toward-the-sun-a11pl3z/ One...
