Torica Astro Globe


Accession Number: 2019.ast.279


This is a large clear plastic celestial globe with a small terrestrial globe in its centre. The base is circular and made of wood; this has been painted yellow. The globe stands on three metal legs formed out of thick rods which have been fixed to the circular base with screws. These three legs are connected at the centre by a cylindrical plastic section.

This section supports a circular metal ring on a vertical orientation. Inside this, there is a smaller pale-green plastic ring with a raised scale molded on it (a meridian), that also goes all around the globe; this can slide so the inclination of the celestial globe can be altered. This is graduated in degrees, and labeled a ten-degree intervals in pairs of quarter-circles; one side is marked from 0 to -90 0, the other 0 to “+90” to 0 (although there is no marking at the “90” position). Between these two full rings there is a semi-circular ring, graduated in regular sections, over the top hemisphere of the globe; this can be rotated independently from the north pole, allowing it to be used over the globe.

Also connected to the outer ring there is a horizontally oriented green plastic ring, molded with a scale, that also goes around the globe (the horizon band). This is also graduated in degrees, and labelled in ten degree intervals from 0 to 360, with “S” marked on one side and “N” on the other.

At both the north and south poles of the globe, curved to sit close on the globe’s surface, there is affixed a circular grey plastic ring with a raised scale labelled in 24 equal graduations marked on it.

The metal ring and meridian combination supports the outer globe at the south and north poles. The outer globe is formed of two hemispheres of clear plastic, fitted together at the equator. Around the equator there is a band of residue suggesting there was once tape around the circumference. Molded on the interior surface of the outer globe, there are markings indicating stars and celestial bodies, a dotted area indicating the milky way, and other significant features; major stars of constellations are marked in yellow. Most of these are labelled with Messier numbers (e.g. “M34”). Major constellations are labelled. Areas of the sky are divided up by dotted lines. The ecliptic is marked by a band and a dotted line. In the lower hemisphere of the celestial globe, there is a round hole through which the interior components can be reached; this is covered by a circular cover which is held in place by crossing plastic strips. This contains a key for the various symbols on the celestial globe.

At the centre of the celestial globe there is a small terrestrial globe. This is fitted onto to a rod that runs from the north to south pole of the celestial globe and through the north and south poles of the terrestrial globe. When the celestial globe is rotated, the globe remains in place. The globe is covered in paper strips fitted together, on which continents, some countries, oceans and other major features are printed in blues, yellows and greens.

Around the globe, about 2 and 3cm distant from its surface respectively are a pair of wire rings; the inclinations of these can be altered. These are connected via rigid wires to the base of the celestial globe, allowing these ‘orbits’ to rotate with the outer globe.

Also inside the outer globe there are two small balls, one yellow and one red, with the red one about 1cm in diameter and the yellow about 0.5cm. Each of these is fixed to the end of one of two curved rigid wires which are connected at the other end to a knob affixed to the celestial globe just next to the globe’s north pole.

This globe was likely designed to teach students about the features of the night sky, and to do basic astronomical calculations. The central terrestrial globe would help with the visualisation of positions of celestial bodies and features from the Earth. The role of the internal smaller balls is unknown.


Poor: The base of the globe is an alteration, likely to stablize the globe; it is marked with small dents, and pen/pencil marks. The metal surface of the legs is in good condition, as are the metal support ring and other metal components, except for the semi-circular ring between the support ring and meridian, which is slightly corroded.

The plastic of the meridian and horizon rings is in good condition, with a few small nicks on the exterior edges. However, the meridian is split through near the north pole; this has caused the meridian to separate from the external support ring and and the graduated internal semicircular ring; subsequently, the globe is no longer supported and has fallen so the globe exterior rests directly on the cylindrical section at the top of the legs. It is very unstable.

The celestial globe is dusty and clouded. There is a band of residue around the equator where the two hemispheres were once apparently taped together.

The interior components appear to be in good condition. However, other models appear to have small pieces of foam affixed to the orbital ring pieces, which this model does not have. It is not clear if these are missing or were never present on this model.

This globe was likely purchased for teaching by the Department of Physics or the Department of Astronomy & Astrophysics at the University of Toronto. In the 2000s, it was found in a room in the McLennan Physical Laboratories building on the U of T St George campus, and moved to the Astronomy Library for storage and display.
