`+1` I wish I could find a *photograph* of an old transparent celestial sphere globe with the ecliptic horizontal and a small earth at the center, tilted. I further wish that it were high-enough resolution that one could see Earth tilting towards Orion. I wish for world peace and for all my SE reputation to change 1:1 for bitcoin, but that's beside the point.

<p>On which side does the earth tilt to? I have tried figuring it out myself but I can't seem to find the answer.</p>

Your question is a bit vague. The North Pole points towards the North star, Polaris. The plane of the equator is (currently) tilted by 23°26′12.0″ relative to the Earth's orbital plane. There's a diagram in my answer [here](https://astronomy.stackexchange.com/a/35118/16685) which may be helpful.

If we call the ecliptic the "floor" then Earth's north pole tilts towards Orion. See  https://commons.wikimedia.org/wiki/File:AxialTiltObliquity.png or http://slittlefair.staff.shef.ac.uk/teaching/phy115/session2/sunMotion/ecliptic/ecliptic.html **voting to keep open** in this case because I think the OP needs some assistance first, before they can refactor the question sufficiently In this case an answer would do the job better than a bunch of comments, and **closing blocks answers**

Hi @Jackson, would an answer like "towards the constellation of Orion" make sense to you? Is that the kind of answer you are looking for? Others are having trouble with your question because right now they are probably thinking "Tilted with respect to what?" There are several coordinate systems but none are absolute, so we always need a reference system. Can you think about "Tilted with respect to what?" a bit? Thanks and Welcome to Stack Exchange!

The equator (Earth's rotation plane) and ecliptic (Earth's solar orbit plane) cross at the vernal equinox ♈, the zero point of both [right ascension](https://en.wikipedia.org/wiki/Equatorial_coordinate_system) and [ecliptic longitude](https://en.wikipedia.org/wiki/Ecliptic_coordinate_system).

Relative to the ecliptic, the Earth's north pole is tilted toward ecliptic longitude *λ*=90°, where the Sun appears at the June solstice.
Constellations in that general direction are highest around midnight in December and January: Auriga, Orion, etc.

The Earth's south pole is tilted toward ecliptic longitude *λ*=270°, where the Sun appears at the December solstice.
Constellations in that part of the sky are highest around midnight in June and July: Sagittarius, Ophiuchus, Hercules, etc.

Even though [axial precession](https://en.wikipedia.org/wiki/Axial_precession) changes the celestial poles' orientation relative to the stars in a cycle of about 26,000 years, their ecliptic longitudes with respect to the equinox of date are constant.
The north and south *ecliptic* poles precess by much smaller amounts and have constant right ascensions *α*=18h and *α*=6h respectively, relative to the equinox of date.

[Stellarium](http://stellarium.org/) might help you visualize all this.
In the View window, Markings tab, you can ask it to plot the equator, ecliptic, and celestial and ecliptic poles of date.
