Context :

Aims : We studied the rotational properties of the dwarf planet Makemake .

Methods : The photometric observations were carried out at different telescopes between 2006 and 2017 .
Most of the measurements were acquired in BVRI broad-band filters of a standard Johnson-Cousins photometric system .

Results : We found that Makemake rotates more slowly than was previously reported .
A possible lightcurve asymmetry suggests a double-peaked period of P = 22.8266 \pm 0.0001 h. A small peak-to-peak lightcurve amplitude in R -filter A = 0.032 \pm 0.005 mag implies an almost spherical shape or near pole-on orientation .
We also measured BVRI colours and the R -filter phase-angle slope and revised the absolute magnitudes .
The absolute magnitude of Makemake has remained unchanged since its discovery in 2005 .
No direct evidence of a newly discovered satellite was found in our photometric data ; however , we discuss the possible existence of another larger satellite .

Conclusions :
