  Remote-sensing observations of Solar System objects with a space telescope
offer a key method of understanding celestial bodies and contributing to
planetary formation and evolution theories. The capabilities of Twinkle, a
space telescope in a low Earth orbit with a 0.45m mirror, to acquire
spectroscopic data of Solar System targets in the visible and infrared are
assessed. Twinkle is a general observatory that provides on demand observations
of a wide variety of targets within wavelength ranges that are currently not
accessible using other space telescopes or that are accessible only to
oversubscribed observatories in the short-term future. We determine the periods
for which numerous Solar System objects could be observed and find that Solar
System objects are regularly observable. The photon flux of major bodies is
determined for comparison to the sensitivity and saturation limits of Twinkle's
instrumentation and we find that the satellite's capability varies across the
three spectral bands (0.4-1, 1.3-2.42, and 2.42-4.5{\mu}m). We find that for a
number of targets, including the outer planets, their large moons, and bright
asteroids, the model created predicts that with short exposure times,
high-resolution spectra (R~250, {\lambda} < 2.42{\mu}m; R~60, {\lambda} >
2.42{\mu}m) could be obtained with signal-to-noise ratio (SNR) of >100 with
exposure times of <300s.
