No they're not. They can't be expressed analytically. Only by numerical integration for a given time frame.

How about:
The Moon has an atmosphere (actually two - one predominately consisting of sodium and potassium ions due to micrometeroid bombardment, the other a dust atmosphere with dynamics governed by electrostatic levitation).
There appears to be ice on Mercury.
The barycentre of the Sun and Jupiter lies outside the surface of the Sun - in other words they clearly orbit each other.
There are tides on the Moon.
As its orbit is so elongated, Pluto's atmosphere solidifies on the surface and then sublimates back to gas during the course of its orbital year.
Many solar system bodies are in orbital or spin-orbit resonances with each other (explains the apparent stability of their orbits).
The power output per unit volume at the centre of the Sun is significantly less than that of an idle human being.

It takes around eight minutes for photons to reach Earth from the Sun, however it can take millions of years for photons to travel from the centre of the sun to its surface.

The energy that the photon (from the core) represents but not the photon itself.

They are tidally locked to each other. There's no such thing as one body only being solely tidally locked to another. It's give and take.
The lunar regolith experiences a tidal variation of up to about 10cm throughout the month - contributions to this coming from the Earth and the Sun (of course) due to the elongation of its orbit about both. This tide leads to some types of moonquakes, weaker and more infrequent than earthquakes but typically longer in duration. Terrestrial rock is wet and sponge like by comparison so damping earthquakes. The Moon is more rigid and rings like a bell.

Elongation of the orbit innit. Well that plus a little contribution from the lunar axial tilt and Earth's rotation.
And an excuse to repost the funky animated gif.

if you sent a typical urbanite to mercury without a space suit they would last 93 seconds after descending from the vehicle to the chillly side of the planet; 5.7 seconds on the sunny side.

Read once that if Jupiter's mass was just 50 times greater it'd be a star.

Technically something closer to 100. But it's a 'grey' area. If it were about 10 times more massive it could be classed as a brown dwarf (which is not a true star, but sub-stellar).
The low end for stars if about 1/10th the mass of the Sun. The upper end is something like 150 or 200 times the mass of the Sun, though the physics is not well understood at that end of the range. There were probably a lot of very (even more) massive stars in the early universe.
Sun facts:
The outer atmosphere of the Sun is far hotter than the surface.
The Sun produces more energy per second than humans have created/consumed since the dawn of mankind.

No. From the Apollo 16 audio transcript:
3m40s into this audio recording.
They'd been drinking potassium spiked orange juice which had been 'prescribed' to the astronauts for other reasons.
In fact astronauts belch and fart all the time. The belches tend to be 'wet' ones because all the stomach contents float near the upper valve in the stomach and not just the gas. Correspondingly, less gas is belched away so more tends to come out the other end.

I shudder to think. That place was very cramped - as is the Russian half of the ISS. There's a guided tour video of the place on youtube. The NASA/ESA/JAXA half is spacious and brightly lit. The Russian half has doors barely big enough to squeeze through, there's pipes and ducts all over the place and it looks like it was designed in the 60s.

The Thrint Kzanol, while returning from his discovery of a new sentient species, experienced a failure of his ship's drive, which prevented the ship from decelerating. He aimed himself at the food-yeast world of F124, and his ship at a moon of the system's eighth planet. The ship's collision with the moon tore it from its orbit, forming the planet known as Pluto*. Encased in a stasis field, Kzanol collided with F124, later known as Earth.
