Interstellar spaceship simulator
for astronomical education
and communications
2007 Jul. 15
Tomonori Nomoto
Interactive simulation of
the interstellar space journeys
Hipparcos and Tycho catalogue, 1997
enabled 3D simulation outside of solar system,
Mitaka, Partiview, StarStrider, Celestia,… etc.
HippLiner… 2001
Originally,
 Constellation line drawing software
for solar system simulator.
Currently,
 HippLiner is an Interstellar spaceship simulator
 Interstellar jouney in the Science Live Show “ UNIVERSE ”
 Free software. Not commercial software.
HippLiner … Interstellar spaceship simulator
Scientific data included:
 Stars near the Sun … 117954 stars
The Hipparcos and Tycho Catalogues, ESA SP-1200, 1997.
The Hipparcos input catalogue, ESA SP-1136, 1992. (radial velocity)
 Open clusters … 601 clusters
New Catalog of Optically Visible Open Clusters and Candidates, Dias et al, 2002.
 Galaxies … 2365 galaxies
Nearby Galaxies Catalogue, Tully, 1988.
Special Features:
 3D stereoscopic view is possible for liveshows.
 3D Constellation line writing function
enables drawing your original constellations.
 Proper motion simulation under approximation of linear motion.

3D interstellar journey.
Sky-view observed from outside of the sun.
New Catalog of Optically Visible Open
Clusters and Candidates, 2002
Nearby Galaxies Catalogue, 1988
601 clusters
2365 galaxies
Position of the open clusters or galaxies are also observable.
3D Constellation drawing
Constellation drawing
88 constellations of IAU
 Chinese constellations
 Your original constellations or lines

Proper motion approximation

3D simulation of proper motions under an
approximation of linear motion for 15672 stars
with proper motions and radial velocities.
Recent improvements of HippLiner…
Actually, currently working and almost finished.

Star color


Using black body
radiation and CIE XYZ
color matching functions
Relativity theory effect
Doppler shift
 Aberration
 Proper time

Originally 0th magnitude .
Data needed for future plan
Infrared, radio wave data of the space is needed.
 For 60 second journey to αCentaur,
99.99999999999% of light speed is required
 With high speed, stars become darker.
Point light source with originally 0th magnitude (V) for each temperature.
In science live show, “ UNIVERSE ”
In the section of Interstellar Cruising
e.g. Nightview from αCentaur, or other stars

Sirius and Betelgeuse becomes very close

Tanabata(七夕): long distance of lovers
A Chinese legend says…
Separated cowherd (Altair) and weaving princess
(Vega) meet through a bridge of magpies over milky
way once in a year on Jul. 7th.

Magpies comes from quite far place!!

Simulations of 3D proper motion
Function of Simulating relativity theory effect including
doppler shift, aberration and proper time as a real
spaceship simulator is to be released near future.
HippLiner is a free software. You can download from
